[chunithm] SUN+ and SUN Omnimix support, split into International and JP versions

[beer-psi]

Changes

• Split versions into separate regions. This was done because each region has their own release schedule, and sometimes songs would release in International first (WACCA collab, HARDCORE TANO*C collab).
• Properly mark 5 songs (LAMIA, 雷切-RAIKIRI-, フリーフォール, Invisible Frenzy, Quon) as from versions SUN International and SUN PLUS
• Added all SUN PLUS songs to date
• Added all SUN PLUS International songs (including the new TANO*C collab)

Todo

• Find all the omnimix opts to import (Done: ANEW, A114, ASAN, ASUN)
• Difficulty folders (BASIC, ADVANCED, EXPERT, MASTER, ULTIMA)

Marking as draft in anticipation for new content tomorrow (King of Performai qualifiers).

Undrafting because the KoP qualifier (and the bonus song) comes on 2/11, not yesterday like I initially thought.

why does the tachi-repo-bot sometimes double comment and sometimes not comment at all. there are clearly relevant changes on this PR. @tachi-repo-bot please do your job

merging even with errors so that it can fail gracefully on staging. it's a flakey test that's been flakey for nearly a year and i've finally gotten around to maybe fixing it. It's a JS async issue. good fun.
