CRS Planck Layout

Goals:

*Maximum compatibility with standard keyboards

I have to work on other staggered Qwerty keyboards all the time so I wanted to keep essentially the same layout instead of optimizing too much.
Trying to fit as many characters as possible on the default layer
- its easier for me to remember logical functions than characters
- Using the extra punctuation caps in place of arrows frees up some Row 4 caps
- however, I'm trying out an arrows layout with the other punctuation on the Raise layer and it is quite nice too
A number pad AND a number row
