e3b4aebf1a Introduces the Disk II as a unique media target platform. 
As it makes a little more sense to analyse Apple GCR images to determine target platform than it does to have the potential platforms vote over them.

Also starts on the parser that'll be necessary for making a decision.

5e34c1b6b8 Switches to producing a single segment for NIBs and DSKs. 
I've now seemingly verified that the values read back by the CPU are those I'm intending to produce, so I'm at a loss.
