Encode type before header, simplify access to pixel data #6

  1. Encode type before header, simplify access to pixel data 

    Write encode type to the second pixel in the encoding sequence as raw
bits (just as with BPC) before the fully encoded header. This allows
automatic detection of the encoding type by the decoder and greater
flexibility for future encoding strategies, given that all reading/
writing procedures after reading the first two pixels can be implemented
differently based on the type value.

Use PxAccessRead and PxAccessWrite to greatly simplify argument passing
and initialization of pixel reading/writing facilities, as well as
automatically handle reading/writing the first two meta pixels (BPC &
Encoding Type).

Also adds a couple tests that check for proper operation when filling a
medium near to or at full capacity, where dropped data or heap
corruption is a concern if pixel access is improperly designed
