Added Nidec CAS 120A footprint
Nidec Copal CAS 120A switch footprint, for Nidec Copal CAS-120A1 switch. Switch symbol based on SW_SPDT, so it is using those pin numbers. So to match datasheet for NO/NC connections Pin 1 and 3 are swapped on footprint (pin 2 is common). Let me know if there is a better way to achieve this.

There is no pin 1 indicator in silkscreen because the component only fits one way.
(symbol is another merge request, I'll add a link once it's made and I figured out how)
