`nflverse_download()` should provide an argument to reload specific data from a release about nflreadr

So what I want is to make this code

nflreadr::nflverse_download(
  pbp, 
  folder_path = "some_path", 
  file_type = "parquet",
  use_hive = TRUE,
  reload = 2022
)

to only download 2022 pbp into the correct folder.

I am an idiot. A timestamp check is included. The function will only download if something has changed
