Please move this into the screenruster repo

Maybe Cargo Workspaces would be a good fit for it?

The current solution is kind of bad for automated building, as one needs to checkout two repos and align the revisions manually + renaming screenruster-saver to screenruster or patching the Cargo.toml from screenruster. Like, there is releases in screenruster, but not in screenruster-saver. If both is kind of part of a bigger something, it should be in one repo IMO - and there is ways of doing that without giving up having the too of them being not the same crate.

Edit:
At least add relases matching the screenruster releases to this repo
