Euroleague-api

Three main changes:
1. Added two functions `get_pbp_data_with_lineups_single_season` and `get_pbp_data_with_lineups_multiple_seasons` for fetching PBP data enriched with team lineups for all games in as single season and in a range of seasons respectively.
2. Fixed a bug in lineup estimation, when the same player is subbed in and out.
3. Fixed pandas futurewarning.

Fixes in docstring for better readability

Major refactoring of the lineup data due to edge cases and bugs.
Minor, default arguments added in a couple of teams and player stats functions.

We fixed futurewarning from pandas 2.1.0. Also fixed the broken links on the documentation on pypi.

Added lineup data which enrich the existing play by play data. Also, started the addition of advanced team stats such as number of possessions and pace for individual games.

Major refactor of the code to allow for EuroCup endpoints. Code is refactored in classes for easier use.
