[MISSED MIRROR] Include temporary library for getting sleeping procs (#77773) (#23258)

* Include temporary library for getting sleeping procs (#77773)

@LemonInTheDark wanted this to be able to hunt down the progress bar
hard dels.

Code is here:
https://gist.github.com/Mothblocks/06b415afd75672fb03637804435350d2

Intended to be reverted once we figure out the issue, or if we realize
it's not related. This library is not stable.

* Update tgstation.dme
