[FEATURE] Add HitSelect module or add it to KillAura to make it an customizable config

Describe your feature request.

You can add HitSelect to KillAura (like the OldFDP client) into an customizable config or turn it into a module on its own (like Slinky and other ghost clients), it can reduce knockback, which I think would be useful in PVP.
