Fab automation (#2)

- Use KiKit for fab automation
- Add splitflap scripts for exporting pcb pdfs, and switch to splitflap script for 3d rendering (for consistency with fab automation)
- Added support in 3d rendering scripts for soldermask & silkscreen colors, option to skip virtual components
- Added silkscreen to base and screen pcbs for commit and date info
