feat: auto generate missing endpoints

[pcriadoperez]

This PR looks to create a script that scrapes the changelog of binance for all exisitng endpoints, and generates the code in python-binance for those missing endpoints.

• Searches latest docs changelog for existing endpoints
• Adds to Endpoints.md
• Checks if endpoint already exists if not it adds function to client.py and async_client.py
• Adds docs specifying an autogenerated function
• Once functions are created they can be edited and changed and won't autogenerate again.

Known issues:

• Assumes all endpoints are private.
• I tried for each endpoint to find the website to autogenerate the docs using openAI and to see if it's a signed or not, however I removed the feature as for a lot of the endpoints that show in the changelog there is no spec or doc available.
• Missing /futures prefix, I will add in a future PR as larger change is needed to admit prefix.

Alternative considered:

Instead of trying to search if the current function exists with a different name, it might be an interesting alternative to autogenerate all endpoints with default name for consistency.

Logs:

Found 4 deprecated endpoints in the docs.
Found 587 unique endpoints in the docs.
Filtered out 8 endpoints that don't match known prefixes
Remaining endpoints: 579
Added 431 endpoints to Endpoints.md
284 endpoints were added out of 579 scrapped in client.py
285 endpoints were added out of 579 scrapped in async_client.py
