New rack and pinion focuser

As part of my CDK250 development, I managed to get precision rack and pinion mechanisms manufactured through Alibaba and then I was able to make my own RP focuser.

I'll update the CDK250 thread, if I can find it, to explain the rationale.
Meanwhile here are some photos I took today.
