Also I have realized there is actually **some** space for
near jump instructions, so I have filled this space out.
Now we can jump forward up to 8 instructions and backward
up to 4 instructions (does not sound very useful though).
I am 100% sure I am missing something important here.
Also of course there is no design for instruction encoding,
so there is a possibility this ISA will not fit into
8-bit instructions.
