Add data from games teams play OUTSIDE the PL

[PhuruShekar]

To be able to gauge more relevant "form" and other data, adding data from CL/Europa/FA/EFL Cups could help others build a more accurate model of players form or teams form for their analysis in FPL.

Potential Data sources for this new data: https://fbref.com/

That is a very good idea! I will try to relate the data from fbref with the fpl data. Right now I am a bit busy but I will definitely take a look into this!
