Feature request: export raw RGB data to TIFF

[thetalkingdrum]

The other post about panorama stitching got me thinking:
NegPy's first step, as far as I understand it, is just decoding the source file (camera raw, Pakon, whatever) into raw linear RGB data.

Would be nice to expose that step as its own export option, so this raw RGB data could be just dumped straight to a TIFF file.
Kind of like the MakeTiff app does.

Since NegPy already does the decoding I figured it might not be very difficult to implement. Right now it only reads camera raw and Pakon that I'm aware of, but if you end up supporting some other exotic formats in the future (.fff Noritsu etc.) this would effectively turn it into a handy converter for them too.

DNG/JXL as extra output formats could be worth discussing later, but I'd keep this request to TIFF for now.
