bcc5057ad3 lightbar: interpreter additions to encode other patterns
Makes a significant encoding change to existing opcodes and
adds several opcodes to allow for encoding the more complicated
patterns that we have on the lightbar (S0, etc.) as well as
condense the ones we technically could encode but couldn't
fit in the 192-byte footprint allotted to us (KONAMI).

We need this to remove sequences from the EC code.

28891eaaab lightbar: treat HALT like a normal opcode
This removes the special casing around HALT. It saves us a string
literal and some logic. In total, we gain about 50 bytes and a
little cleanup for this.

BUG=None
BRANCH=ToT
TEST=Tried a program that uses HALT (i.e. red-green-blink) in
  simulator and on hardware.
