Type-level function to recover the OptionalPad types from a generic set
of Pads
This trait is used as an interface between the Pads type and other
types in this module. It acts as a type-level function, returning the
corresponding Sercom and OptionalPad types. It serves to cut down on
the total number of type parameters needed in the Config struct. The
Config struct doesn’t need access to the Pins directly. Rather, it
only needs to apply the SomePad trait bound when a Pin is required.
The PadSet trait allows each Config struct to store an instance of
Pads without itself being generic over all six type parameters of the
Pads type.
