Feature to import wave based Soundfonts and Instrument formats

[Foreverorneverror]

Furnace already has an option to assign different samples to an instrument, but it would've been significantly easier to manage instruments relying on multiple samples (waves), if there was an option of importing legacy instrument formats or/and soundfonts.
I see no downsides to this QoL feature, especially given how many different PCM and wavetable based chips are already supported by the tracker.
Suggested Instrument/SF formats, I'd like to see supported in some form or another:
SFZ
SF2
SF3
SFOGG
ITI
DLS

It could be useful, but envelopes might be tricky... I suppose those could be ignored in favour of just letting the user set them up maybe?
