This adds support for the nintendo switch online controllers which
include the SNES, Genesis, and N64 Controllers.

As each nso controller only implements a subset of what a pro
controller can do. Each of these 'features' were broken up in to
seperate functions which include right stick, left stick, imu, and
dpad and depending on the controller type that it is, it will call
the supported functions appropriately.

Each controller now has a struct which maps the bit within the hid
in report to a button.

The name given to the device now comes directly from the hid
device name rather than looking up a predefined string.
