CR Touch CR-200b

Remix of the BL Touch design to accommodate a CR Touch (I assume it still works with BL Touch as well) .

I made the following changes:
- made the screw holes smaller to fit the m3 screws included with the CR Touch
- made a cutout so that the cable connector on the CR Touch is accessible
- removed the top cable brackets so it can be printed without supports (if flipped on the top)
- added slots for zip ties that come with CR Touch for cable management
- updated label to signify CR Touch instead of BL

I have tested the design and it works, but there are a few modifications that need to be made in your slicer to get it all together.
- My offsets had to be changed to Z-3.0 X30 Y33 (note that I am on an aftermarket hotend (micro swiss), so your offsets may be different
- Had to change my build plate size to a max of 180 for Y to prevent the CRTouch from banging into the back of the printer. You may be able to bump this up a little, but the issue still occurred for me at 1
