Allow installing a package from a github release

[Clockwork-Muse]

I'd like to install a github release that only has platform packages (eg, deb,rpm), and no binaries/zipped binaries.
(The particular repository is emqx/MQTTX, but there are possibly more. The repo does have cli-only binaries, but I want the GUI package)

Obviously there are other ways to get the package installed, but having the version resolving feature is what makes it more handy. Specifying the binary does get it downloaded, but that sticks it in the wrong location, and obviously doesn't unpack it.
