**Summary**
Use more sophisticated algorithm for splitting oversized `Table`
elements into `TableChunk` elements during chunking to ensure element
text and HTML are "synchronized" and HTML is always parseable.
**Additional Context**
Table splitting now has the following characteristics:
- `TableChunk.metadata.text_as_html` is always a parseable HTML
`<table>` subtree.
- `TableChunk.text` is always the text in the HTML version of the table
fragment in `.metadata.text_as_html`. Text and HTML are "synchronized".
- The table is divided at a whole-row boundary whenever possible.
- A row is broken at an even-cell boundary when a single row is larger
than the chunking window.
- A cell is broken at an even-word boundary when a single cell is larger
than the chunking window.
- `.text_as_html` is "minified", removing all extraneous whitespace and
unneeded elements or attributes. This maximizes the semantic "density"
of each chunk.
### Description
If the id value exists in the stats response from fsspec, save it as a
`file_id` field in the metadata being persisted on each element.

The Dropbox source connector currently raises exceptions when indexing
files due to two issues: a path formatting idiosyncrasy of the Dropbox
library and a divergence in the definition of the Dropbox libraries
fs.info method, expecting a 'url' parameter rather than 'path'.
## Changes
* add a `/` prefix to file path used by DropboxIndexer
* override the fsspec sterilize_info method in DropboxIndexer to call
`self.fs.info` with `url` rather than `path`; to accommodate for the
fact that `dropboxdrivefs` diverges with this signature
* remove `dropbox.sh` from ignored source tests
* update test fixtures (now that the dropbox connector has been fixed
and not skipped)
## Testing
`dropbox.sh` source ingest test now succeeds (and is no longer ignored)

### Summary
Rip off page_number metadata fields until we have page counting for all
kinds of html files (not just limited to news articles with multiple
`<article>` tag)
### Test
Unit tests
`test_add_chunking_strategy_on_partition_html_respects_multipage` and
`test_add_chunking_strategy_title_on_partition_auto_respects_multipage`
removed since they relay on the `page_number` fields from the SEC html
file - now test moved to mock test for chunk_by_title -> revisit those
tests when we find test file for this
Also changed the element ids from partition outputs for html files -
element id change due to page number change (in element id hashing) ->
todo ticket: update other deterministic element id tests per crag's
comment

Part two of: https://github.com/Unstructured-IO/unstructured/pull/2842
Main changes compared to part one:
* hash computation includes element's sequence number on page, page
number, document filename and its text
* there are more test for deterministic behavior of IDs returned by
partitioning functions + their uniqueness (guaranteed at the document
level, and high probability across multiple documents)
This PR addresses the following issue:
https://github.com/Unstructured-IO/unstructured/issues/2461
Addresses a cluster of HTML-related bugs:
- empty table is identified as bulleted-table
- `partition_html()` emits empty (no text) tables (#1928)
- `.text_as_html` contains inappropriate `<br>` elements in invalid
locations.
- cells enclosed in `<thead>` and `<tfoot>` elements are dropped (#1928)
- `.text_as_html` contains whitespace padding
Each of these is addressed in a separate commit below.
Fixes#1928.

Canonicalize JSON produced for ingest tests such that incidental changes
is _form_ of the JSON objects (keys moving around) that does not change
the _content_ of that JSON object does not trigger an ingest-test
failure.
### Description
* Priority of this was to fix deserialization of ingest docs. Currently
the source metadata wasn't being persisted
* To help debug this, source metadata was added to the local ingest doc
as well.
* Unit test added to make sure the metadata itself was persisted.
* As part of serialization, it was forcing docs to fetch source metadata
if it hadn't already to add to the generated dict/json. This shouldn't
have happened if the underlying variable `_source_metadata` was `None`.
This way the doc can be serialized without any calls being made.
* Serialization was moved to the `to_dict` method to make it more
universal.

### Summary
Closes#1534 and #1535
Detects document language using `langdetect` package.
Creates new kwargs for user to set the document language (`languages`)
or detect the language at the element level instead of the default
document level (`detect_language_per_element`)

Adding table extraction to HTML partitioning.
This PR utilizes 'table' HTML elements to extract and parse HTML tables
and return them in partitioning.
```
# checkout this branch, go into ipython shell
In [1]: from unstructured.partition.html import partition_html
In [2]: path_to_html = "{html sample file with table}"
In [3]: elements = partition_html(path_to_html)
```
you should see the table in the elements list!
### Summary
Closes#1230. Updates `partition_html` to split on `<br>` tags that
appear within text elements.
### Testing
The following is code previously produced one giant element on `main`.
```python
from unstructured.partition.html import partition_html
filename = "example-docs/ideas-page.html"
elements = partition_html(filename=filename)
len(elements) # Should be 4
print("\n\n".join([str(el) for el in elements)])
```
The output should be:

(Someone fed my essays into GPT to make something that could answer
questions based on them, then asked it where good ideas come from. The
answer was ok, but not what I would have said. This is what I would have said.)
The way to get new ideas is to notice anomalies: what seems strange,
or missing, or broken? You can see anomalies in everyday life (much
of standup comedy is based on this), but the best place to look for
them is at the frontiers of knowledge.
Knowledge grows fractally.
From a distance its edges look smooth, but when you learn enough
to get close to one, you'll notice it's full of gaps. These gaps
will seem obvious; it will seem inexplicable that no one has tried
x or wondered about y. In the best case, exploring such gaps yields
whole new fractal buds.
```
