IO: Remove the RPI (Raspberry Pi) class
This provided constants that translated from the physical header pin numbers to GPIO lines. Instead, we (and the majority of other Pi related documentation out there) now just use GPIO numbers exclusively. The class hasn't been used in examples since a few versions, and also wasn't ever properly documented in the reference, so unlikely that many people will notice.
