[RFC] dropprs - priviledge de-escalation POC for stash-s6

I’ve been struggling with process de-escalation (VAAPI GID mismatch · Issue #40 · feederbox826/stash-s6 · GitHub)

and have instead decided to make my own solution - dropprs GitHub - feederbox826/dropprs: Rust utility for dropping permissions

I would appreciate any and all feedback as this will be an essential part of stash-s6 in de-escalating from the root user.
