[MIRROR] Adds custom icon mapping helper. (#2748)

Browse Source 
* Adds custom icon mapping helper. (#56183)

Allows embedding icon edits in your maps by fetching them from external host.
This is intended for use with live-loaded away/event maps not standard ones.

Also updates rustg defines to expose the additional options arguments. (https://github.com/tgstation/rust-g/pull/59)

* Adds custom icon mapping helper.
