compress old versions of tracks #84
Description
LRA keeping every copy of a track that you save is great for archival purposes and works very well because of .trk files sizes, but gets especially out of hand for cases with larger track files (i have a track i saved less than 100 times where the folder is 1 GiB)
i think it would work well for LRO to keep only the latest copy uncompressed and gzip the rest, but maybe as something opt-in since it could be annoying and incompatible with previous LRA builds.
i tested also combining many track files into a .tar to compress them since their similarity should make the compression ratio significantly better but it really didn't have that effect in my testing. i think some kinds of specialized compression can do that optimization but xz and gzip didn't seem to
