Build script now runs deps.sh before building to prevent running commands that aren't available.

Script now compiles csg files. TODO: fix the csg2step.py script by using latest FreeCAD logic.
Script allows for input of a size (50ft/100ft) or an part (from FILES) to render fewer files.
Migrate bulk of the loop into a render_part() function that can be re-used.
