Update rust-g, use spritesheet asset for design icons (#5315)

* Update rust-g and fix spritesheet icon cache problem

* Convert design_icons to spritesheet, from 1618 images to 8

* Update rust-g in the CI as well

* Push ci suite to ubuntu 22.04 so that rust-g stops complaining

* Update libssl too... oh jeez.

* Fix PyYaml

* Include rust-g in repo for CI

* Stop CRASHing whenever the asset cache encounters a bad entry, it guarantees everything else will break

* A whole bunch of bullshit to make IconForge work

Ports BeeStation/BeeStation-Hornet#10404

* whoops this should be in the example config
