Currently, def_fumbles is a bit of a misleading phrase because it includes punt return fumbles, since the returning team is the defensive team.

Describe the solution you'd like

I'd like the fumbles logic to mirror the TD logic in this function. In particular, for TD's:

def_tds → team == def & special != 1
special_tds → special == 1

Likewise, I would like to update from
def_fumbles → stat_id %in% 52:53 & team == def to def_fumbles → stat_id %in% 52:53 & team == def & special != 1 plus
special_fumbles → stat_id %in% 52:53 & special == 1

This has the added benefit of cleaning up the relationship between fumbles_total and the subcategories. If we break out this additional special category, I believe it leaves the only instances of fumbles_total not adding up to the subcategories as being botched snap plays or fumbles off of offensive fumble recoveries (I think this works well as other_off_fumbles). Currently, kickoff fumbles are unclassified in any of the subcategories, but special_fumbles would catch it nicely.
