Created public header and added LED identifiers

The LED identifiers are flags which are based on the sequence
in which the LED is illuminated. These flags are intended to be
Bitwise OR'd.

One issue is that the device does not use a continuous region of 18
bits, but instead uses 6 out of 8 bits in 3 bytes. Either the flags need
to be modified, or there needs to be some hidden bitwise logic to shift
the flags the appropriate amount.

The second solution currently seems better
