Procedural testing

[AlvaroHG]

New testing layer for Unity using Procedural houses.

• Transform integer array to 3d polygon equivalent code and tested parity with procthor/houses package.
• New HouseTemplate object for minimal house specification.
• New test organization for future tests, under Procedural, divided by Rendering, Physics and Templates (layouts).
• Testing suite for layouts.

Another PR incoming with Rendering tests.

Further improvements and cleanups of templates in the works.

I did a quick review, looks very nice :)! One thing I was expecting but didn't see was more pixel-to-pixel tests within ProcTHOR houses. Is this coming in a different PR?

Ready for merging, LGTM analysis seems to be hanging, but build passed.

@AlvaroHG Can you open the LGTM link and double-check the 8 Useless assignment to local variable alerts? It would be good to remove these unneeded assignments and double check the logic makes sense without them.

After that, LGTM, please merge.

Merging now, remaining useless assignments are lambda variables that analyzer does not recognize
