NOTE: OPCODES should not be relative, but there should be a relative accessor for addresses, like:
$relative_name JMP
## Notes
### Conditional Jumping
I've considered automatically popping an amount of items from the stack equal to the offset between the opcode's push/pop to make the stack length more predictable, and making the pattern JMP? POP2 unecessary, but that idea would make DUP? unusable. That change was reverted.
## Palettes
