Integrated IPF loader?

[vadosnaprimer]

Every Amiga emulator I checked relies on the SPS library to load IPF images, and it's strictly non-commercial but free to distribute so it's been working fine.

But there is a couple actual open source re-implementations of it, so it might be beneficial to build IPF support straight into the emulator. I don't know the functional difference between CAPSimg and these (if any), so I don't know if it'd make sense to leave an option to use integrated or SPS's one.

https://github.com/mamedev/mame/blob/master/src/lib/formats/ipf_dsk.cpp (amusingly made 4 days before SPS released their code)

I'll think about it. Could be useful when official library is not found. (Official would "win" if found, not going to add any options)
