[SoFIFA] Issue Retrieving Player Ratings

[capo11]

Describe the bug
There are issues retrieving player ratings, because ratings for stats other than overall rating and potential are none.

Affected scrapers
This affects the following scrapers:

• ClubElo
• ESPN
• FBref
• FiveThirtyEight
• FotMob
• Match History
• SoFIFA
• Understat
• WhoScored

Code example
A minimal code example that fails. Use no_cache=True to make sure an invalid cached file does not cause the bug and make sure you have the latest version of soccerdata installed.

import soccerdata as sd
sf1 = sd.SoFIFA(versions="latest", no_cache=True)
sf1.read_player_ratings(team="Inter")
