Added MULS.W functionality and testing, fixed output loop errors

- Added MULS.W opcode recognition and processing
- Added MULS.W opcode testing
- changed all testing addresses again
- fixed output loop errors
  * TO EACH PROCESSING OF AN ADDRESS:
  * JSR PRINT_init
  * BRA loop_exit
- also, some opcodes were incrementing an address more than it needed to be
- some will probably need to be fixed still
- look for the range of addresses next to each marker for testing sections to test the start/end addresses. I've only tested the first one.
