ff_scoringhistory() missing variables

I'm running:

```
FAFL20 <- mfl_connect(season = 2020, league_id = 22686)
structure(ff_scoringhistory(FAFL20, season = 2020))
```

And seeing that:
```
sack_fumbles_lost
passing_first_downs
rushing_fumbles_lost
rushing_first_downs
receiving_fumbles_lost
receiving_first_downs
special_teams_tds
```

are all excluded from the df.
