**Summary**
Eliminate historical "idiosyncracies" of `table.metadata.text_as_html`
HTML introduced by `partition_csv()`. Produce minified `.text_as_html`
consistent with that formed by chunking.
**Additional Context**
- CSV `.metadata.text_as_html` is minified (no extra whitespace or
thead, tbody, tfoot elements).
- `table.text` is clean-concatenated-text (CCT) of table.
