Is your feature request related to a problem? Please describe.
I do not have a way to install quickemu on Project Bluefin (Fedora SilverBlue) via RPM. Homebrew is supported on Bluefin out of the box.

Describe the solution you'd like
A Homebrew formulae to install quickemu on Linux

Describe alternatives you've considered
I could install via an Arch distrobox but running a vm inside a container does not sound smart.
