[aur-general] Removal request for romextract

[beest]

I'd like to request removal for romextract. I sorta became upstream
since it was easier at the time than patching and the source hadn't
been touched in years, but I zapped most of my GH projects long ago so
the source in the (orphaned) PKGBUILD is dead, and it's questionable
whether this belonged in the AUR in the first place (being more of a
collated collection of utilities with mixed/unknown licenses).
