Changelog

Re-export xgboost models to get rid of annoying warning message
Tweak how close to end of game it will calculate probabilities
Required data isn’t loaded directly with the package. Instead the download is triggered when necessary and cached in a local package cache. The cache can be cleared with the new function nfl4th_clear_cache(). The package resets the cache partly when loaded. This can be prevented with options(nfl4th.keep_games = TRUE).
Update win probability model. Instead of only using nflfastR, it stacks nflfastR with another model
Fixup cache paths.
Remove tidyverse from Suggests

Fix for aborted plays on punts being called going for it
Re-categorized some plays as unknown (i.e., NA) go: False Start or defensive encroachment along with being lined up to go for it (run formation or pass formation)
Added fast argument to load_4th_pbp() which allows for loading pre-computed go_boost rather than needing to calculate it

Release as package
Fixes with touchdowns. Instead of granting 7 points, assumes teams choose best option between PAT or 2pt and give pre-conversion attempt WP accordingly
Fix for punt WP at the end of first half being too high
Add logic for TD/FG decision on the last play of the first half
Add possibility for muffed punt
Reduce field goal chances on very long field goals
