Add player_params option for YouTube extractor to customize player requests. Update README.md to document the new option and its usage.

Sing, O Muse, of the cunning code that gave
To mortal users a new option brave
To alter player_params as they please
And thus control the formats of YouTube's streams.

Walkthrough

• Add a new option player_params to the youtube extractor that allows the user to specify custom YouTube player parameters for player requests (link, link, link, link)
  • Remove the hardcoded _PLAYER_PARAMS attribute from the YoutubeIE class and use the user-provided option instead (link)
  • Modify the _extract_player_response method of the YoutubeIE class to use the player_params option or fallback to the default value for android clients (link)
  • Append the player_params option to the query string in the _download_player_responses method of the YoutubeIE class (link)
  • Update the documentation for the youtube extractor in README.md to include the new option (link)
