[Request]: add the option to exclude some generated playlists

[UltimateRiff]

Description

some users (like me) might like to exclude some LB-generated playlists, like a specific Year In Music playlist (like the Top Missed Recordings of 20XX line) or perhaps Year In Music playlists that are older than one year. it would be good to be able to customize the selection of generated playlists downloaded

Proposed solution

the main options I'd personally like to see are:

• exclude old playlists from a certain line (like Top Missed Recordings of 20XX, possibly with a customizable timeframe)
• exclude all playlists from a certain line
• possibly manual exclusion per-playlist, but that's slightly lower priority

Additional context

also, if we get user-created playlist syncing before this, might be good to allow excluding individual playlists too
