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`)

### Summary
Closes#1184. Updates `partition_html` to respect the ordering of
`<pre>` tags in HTML documents.
### Testing
The elements in the following example should be in the correct order.
```python
from unstructured.partition.html import partition_html
html_text = """
<pre>The Big Brown Bear</pre>
<div>The big brown bear is growling.</div>
<pre>The big brown bear is sleeping.</pre>
<div>The Big Blue Bear</div>
"""
elements = partition_html(text=html_text)
print("\n\n".join([str(el) for el in elements]))
```
