There are some commented out FRAME types in sane-backends. They are
not officially supported, as someone may come up with a better
mechanism. I don't know of any image type that would support RGBI,
though it might be possible to use one of the more extensible formats
like TIFF to store an RGB and IR frame separately.

TIFF supports that.
