Add ability to restrict pull script to speed up syncing large media libraries

[joemaller]

IOP's media library, for example, is currently over 5GB and takes an extraordinarily long time to sync down. Needing to implement something quickly could be seriously hindered by having to wait.

Not sure how to do this, but since the uploads directory has a known format, maybe the script could request the current year by default, and then add some sort of pull:uploads-all command to grab everything before that

Another option might be something like npm run pull:uploads 2021 where the year argument specifies which year of downloads to pull. Not sure if that's possible?
