Being a lazy person I decided not to search extensively or code one myself
Anyway, is there a known to work non-windows-only tool that would input popular lossless compressed formats (PNG, GIF, BMP, ..) and spit out an IFF. The twist here is that simple palette cut is required e.g. 256 colors PNG to 8 color IFF
without any "intelligent" processing just take the first 8 colors from the original palette and be happy.
I am about to test

And there's no OSX version of the proggie.
