[Request] Customizable Short/Long Rest Exhaustion Recovery

[sebastienlaughrea]

Is your feature request related to a problem? Please describe.
Tasha's Cauldron of Everything introduces a feature for rangers allowing to recover a point of exhaustion during short rests. This is currently not implemented.

Describe the solution you'd like
This feature could be generalized to allow to customize the amount of exhaustion points recovered during short or long rests.
The exhaustion automation could take a formula defaulted to 1 for long rests and defaulted to 0 for short rests.

Tireless
As an action, you can give yourself a number of temporary hit points equal to 1d8 + your Wisdom modifier (minimum of 1 temporary hit point). You can use this action a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
In addition, whenever you finish a short rest, your exhaustion level, if any, is decreased by 1.

I will not be implementing this, but this module is open source and accepts code contributions from anyone :)
