Increases the experience earned by Hunter Boxing (#93435)

## About The Pull Request

Hunter boxing now uses the full quantity of damage inflicted by your
punches, rather than half. We also multiply our experience based on the
max health of the creature we're punching.

You do not get the exercised status effect for punching mobs with Hunter
Boxing.

You do not earn experience for punching dead things.

Hunter Boxing can now brutalized Crustaceans and Reptiles. This does not
include lizardpeople, as they're humanoid. No, you can't Hunter Boxing
the ashwalkers. Or your lizard QM boss.

## Why It's Good For The Game

It takes a really, really, really long time to level up using Hunter
Boxing. Normal athletics progression is largely kept in line by the fact
that you need to go sleep every time you do a workout session.

Hunter boxing, however, does not allow you to do that because you're
currently trying to punch xenofauna and demons to death while in the
middle of a hell planet and trying not to die.

The fact that fauna fight back when punched means leveling up with
hunter boxing has its own internal complications for preventing
athletics progression from being a walk in the part. Obviously, the
threat of death is its own punishment mechanic.

It's maybe a bit much of an ask miners to be weightlifting when they
should be mining after all.

## Changelog
🆑
balance: Hunter boxing now grants a reasonable amount of experience in
Athletics for punching the absolute shit out of the local wildlife.
balance: Includes crustaceans and reptiles to the list of mob types that
Hunter Boxing is allowed to mangle with their bare hands. You still
can't use Hunter Boxing on lizardpeople. Or crabpeople when they are
added in 2030.
