I didn't think it made sense, but I found something that used it, so apparently it's a thing. This updates the operand editor to let you choose PETSCII+DCI, and updates the assemblers to handle it correctly (really just 64tass, since the others either don't have a DCI directive or don't deal with PETSCII at all). Changed the char-encoding sample from "bad dcI" to "pet dcI", and updated the documentation.
