Operands metadata are inconsistent #11

Closed 64kramsystem closed 1 year ago

For some instructions/opcodes, the operands metadata is inconsistent.

See for example ADD A, B (0x80):

      "operands": [
        {
          "name": "A",
          "immediate": true
        },
        {
          "name": "B",
          "immediate": true
        }
      ],

this is instead SUB A, B (0x90):

      "operands": [
        {
          "name": "B",
          "immediate": true
        }
      ],

the SUB` instruction is missing the first operand.
