Game move functionality

[buswedg]

Would be great to have a command which allows installed games to be moved across different locations, with manifests updated accordingly for the Amazon Games Launcher to remain synced to what is installed (no matter location).

This would be similar to the move functionality offered in legendary. But would be particularly helpful, as I've always had problems installing games to network locations via the actual Amazon Games launcher, which tends to complain about 'restricted install locations'.
