Gives QB credit for EPA for up to the point where a receiver lost a fumble after a completed catch and makes EPA work more like passing yards on plays with fumbles.
Build columns that capture what happens on all plays, including penalties, using string extraction from play description. Loosely based on Ben's nflfastR guide (https://mrcaseb.github.io/nflfastR/articles/beginners_guide.html) but updated to work with the RS data, which has a different player format in the play description; e.g. 24-M.Lynch instead of M.Lynch. The function also standardizes team abbreviations so that, for example, the Chargers are always represented by 'LAC' regardless of which year it was.
