Added BTST, register mode, and corrected a mixup where BTST immediate and register modes were swapped
Added jump destinations as described in https://github.com/JKowalsky/CSS422-Disassembler/wiki/EA-Handler-Documentation
New "megatable" table that contains instruction bitmask, signature, human-readable label, and effective address entry point. The opcode decoder now can decode BTST and NOP, with each instruction+mode requiring only one 3-longword entry in the table. Also updated "simulators" and three instruction unit tests to match latest "API"s.
Added all remaining required OPCODEs to table
Initial version of the OPCODE decoder with MOVE instruction synthesis functionality
Updated BTST, Immediate test and added bit moving and override for EA decoder for this instruction
Added MOVE synth data for ADD and ADDA, revised comments to include addressing modes in the signature table
