[CRITICAL BUG] Crash when importing raw IMA ADPCM sample data

[freq-mod]

Originally reported by Furmillion on Discord, where it was ignored. To reproduce (works every time):

1. select import raw sample option
2. select any file (doesnt have to contain actual PCM data
3. select IMA ADPCM format
4. wait a few seconds, furnace will crash

Example crash log:

Ignored. Let me take a break?

It's fine by me for this, I don't see the problem for me.

Waiting for fix confirmation.
