`git sync` command should output confirmation to host

[pa-0]

When I run git sync inside a repo directory, the command appears to run without returning any kind of output. It would be great if it wrote some kind of confirmation, possibly even adding a -v/--verbose option to confirm per-branch

Hey! So currently the git sync command only prints output if it takes an action (e.g. you can see the Printf calls like https://github.com/jacobwgillespie/git-sync/blob/main/main.go#L76). If there's nothing to update or clean up, then there's no output.
