Generic Rendering

[jmwright]

@julianstirling The build/compile CI Action is giving an error that suggests that I've broken off-screen rendering somehow, and I'm not sure how I did it. I have also somehow broken glb/glTF export, most likely because of the changes I made to generate_assembly_model. I'm not super excited about that change (passing rendering_options around) because it blurs some concepts together, but it was the most direct method I could think of to facilitate the generic rendering mechanism. I'm out of time to work on this right now, and may not be able to get these things fixed before tomorrow.

Closes #100

Do you want me to look at getting the pipeline to run tomorrow?

I finally got it, thanks. I couldn't get xvfb-run to accept the json, but I finally figured out the incantation of escaped quotes to get it to pass through. Going to need a squash on this merge for sure.

If you don't want to squash the whole thing you can do git rebase --interactive master To rebase on the same master it is currently based on. This will bring up a screen where you can select past commits to skip.

@julianstirling I have fixed the bugs that I introduced, but I still have two issues (the second one is minor).

1. I am trying to create a renders directory within assembly-docs to put the png renders. I can see it pop up in the directory listing for an instant, and then it seems to get purged during some sort of cleanup when I run cadorchestrator generate .... I'm assuming this directory needs to be created via a configuration file rather than directly in code, but I'm not sure where to do it.
2. When I run cadorchestrator serve, the browser (Firefox) seems to be caching an old assembly.glb file, even though I've deleted the _cache_ and build directories. I opened the link in a different browser (Chrome) that hadn't seen the file yet, and it came up correctly. I also dragged the assembly.glb file to an online viewer, and it looks correct. As a side note, the online viewer seems to have the correct orientation for the model. The problem with orientation in the viewer is probably a hold-over from when I originally prototyped the UI, unless you redid that code.

@jmwright Is this ready for review?

[jmwright]

@julianstirling Yes, it's ready.

One suggestion as GitBuilding eats the renders after they are generated. Suggested code tested locally here.

A few comments, but they don't need to delay merging.
