HackyVM - Addition

Assume we have a memory map like:
> 001
(Which would be reserved with `alloc 3` and then written to like `write 0b1, 2` to make it look like that)
The way hacky VM will handle addition goes like:
Given an input of
> `add 2, 2`
(these are offsets in the memory map)
the memory map now looks like:
> 010
This opens up some interesting functionality, as you'll see.

Given a memory map that looks like
> 0000111
and the instruction
> `add 6, 6`
the memory map will now look like:
> 0001110
