Edgartools

Fixed
- Fixed bug when downloading data to local storage

Changed
- Refactored the code that used HTTPX client connections to reuse connections. Reusing HTTPX client connections yields about a 20ms savings per request in retrieval in limited tests. (Thanks to paul igmo)
- Consolidated the httpx client connection to a single edgartools.httpclient module. This will allow for more control over the client and the ability to pass the client explicitly to functions that need it.
- More logging statements when downloading filings to local storage
- Set throttling when listing the SEC filing bulk files

Added
- `edgar.company` module to consolidate functions related to companies
- `public_companies` iterator over the public companies in the SEC dcik tickers list

Fixed
- Fix for Form **F-1** files not being detected as HTML

Fixed
- Fix issue with text being inadvertently printed to a notebook
- Allow for filing HTML inside <DOCUMENT> tags to be read as html

- Minor fix for incorrect import statement introduced in 3.8.0
