Add release binaries to github releases for easy use with github actions

[Sycrosity]

Using this project for creating github releases would be really useful and simplify my build workflow significantly - however, currently running the cargo install cargo-bundle command takes around 1-2 minutes of the project time. It would be helpful to have some prebuilt release binaries for a few common targets so that in github actions someone could simply download and run the binary to create a bundle, built alongside each tagged release.

I don't currently have the time to impliment this myself, but in a week or two I could do some testing if this is something that others would like aswell.
