[FEATURE]: Togglable feature for shift = no animiation

[Soapy7261]

Is your feature request related to a problem? Please describe.

Sometimes, I'm just mining down a bunch of trees, and sometimes the animation just slows me down, yeah you can turn it off, but sometimes I want the animation or don't really mind it.

Describe the solution you'd like

Make it a togglable feature to make it so the animation doesn't play when shifting, or vice versa

Describe alternatives you've considered

Using veinminer and configuring it to make it only work when shifting

Additional Information

I was told to make this on GitHub

Two things:

1. We currently don't want to add new features to the "legacy" branch because the new SmoothTimber version will replace it sooner or later
2. Using the crouch control of minecraft to prevent the animation from happening kind of conflicts with the "enable smoothtimber only when sneaking / not sneaking" so that's not really an option imo
