Intelligent track change detection in scanner to preserve primary keys

[tboby]

gonic version: v0.16.2

commit: f98b232

I'm using Picard to tidy up my media library. For some tracks and albums, this involved renaming, although the ids should have remained the same as they were identified already. I'm fairly sure that when I renamed it lost my user ratings. Renaming back didn't seem to restore them.

Gonic remains wonderful, thanks!

this is definitely an issue an quite a tricky one. if a user has a library on the filesystem, then cleans it with picard or beets or whatever, usally both the paths and metadata change. from gonic's perspective the old and new files have nothing in common any more. even the checksum of the files would be new, ofc the paths are different too

i was thinking maybe about reading the mb track ID or mb recording ID but that may well have duplicates and not correspond 1 to 1 with gonic ids

maybe using AcoustIDs help. but that requires all users have them set
