Holds not parsed properly from .DWI

[stiff fractal]

CPU:any
OS::Windows and Linux
Version:Alpha V from website as of yesterday

If a DWI file is loaded in the alpha, a hold like B!B is treated as if it were BB!B which desyncs everything after the hold. All holds are wrong. If it isn’t, it’s because there was already a SM or SSCf file there that had priority

Easiest way to test this is DWInsanity’s sandstorm, which comes as DWI only and starts with that exact hold which turns into a jack jump hold and desyncs the entire chart after.

I tagged it as regression because it works fine in SM5
