[Feature Request] Ability to assign hitdefs to specific hitboxes

[VinVulpis]

Basically, the ability to assign hitdefs to specific hitboxes with priority so that only one will hit in a certain window of time, rather than all of the annoying work arounds that all have side effects, because of Mugen's default limiting behavior of only being able to have one hitdef active at a time.

The idea is to be able to make sweet and sour spots for attacks. Or have attacks do more or less damage based on when in the animation the attack hits.

I've come up with some work around for timing things, but reversals and hit-overrides still kind a break them, making them hit as many times as there are hitdefs (or how often the same hitdef is called)

Like, I have some jump kicks that have a 2-frame sweet window that does more damage at the very start, but then a weaker hit with nochainID for the first hit, side effect, it needs to be parried twice, and hits super-armored targets twice. I want to avoid just turning off the hitdefs so that other targets can still be hit even if the first target armors.

I'd imagine it could be something like a "hitdef group ID" or something. So if one of them hits, the others in the same group can't hit the same target.

Hit boxes do have numbers, so if there were some way to tap into that, it'd be awesome.
