Mining Speed Limiter

QoL mod, prevents over-mining when a key is held down. 
When activated, it adds an interval to insta-mine, like mining in creative-mode.
Keybind is default to ‘LSHIFT’, so it activates when sneaking. Can be set to another key if you want.
Client-sided, no need to install on server-side.
Configurable interval and activation mode: Always active, with keybind, without keybind, or disabled.
