feat: Hawkmoon Trimaran-Class Freighter, playable map

[foxcurl]

Adds the HWKM "Trimaran" Class Freighter, name courtesy of Flux.

A new playable low-midpop map with a few minor gimmicks. One of the most notable ones is that doors are locked only on the outermost bounds of a department (excluding security and any higher-access areas). That is, if you get into a department, you can go just about anywhere in the department. Another significant detail is that there are bedrooms for the majority of the crew (all roundstart); the implication being that in the past at least, people were living on the ship. Sorry engineering. Also features an enormous main hall with conveyors along the center.

Custom cargo shuttle, evac shuttle, parallax, and posters.

Map render.

Cargo shuttle.

Evac shuttle.

Will likely be flyable if the thruster blocks are fixed up. Probably won't fly very fast.

A small peek at the parallax.

i hope you all enjoy and thank you all so much <3
special shoutout to catty for doing review and giving feedback throughout the process, and thanks to flux for providing the wonderful name

I did a walkthrough and ghosted around a bit, and everything looks beautiful! We should keep an eye on the engineering experience, and obviously we'll see how the more experimental aspects play out, but I am very excited to see this map in action.
