nip4 9.0.1-5 (new formula)

nip4 is a rewrite of the nip2 image processing spreadsheet for gtk4:

This repo doesn't yet have the 100 stars that I think homebrew ask for, though nip2 does:

nip2 is popular in the museum and medical imaging communities, so an easy-ish to install macOS build would be very helpful.
