Some GPU Instructions are failing

[DerelictDrone]

Seems to have begun after #27, and isn't fixed by #28

Error that shows up

[ZVM ERROR]: unknown error

For 3D examples, the code is being finalized while it's half finished (trailing "variable +" something from what I could tell by printing the entire emitblock on error)

For other examples(like the trig one), instructions using % for modulo or trying to check if a character is "%" have errors due to string.format attempting to parse them as a replacement.

Needs further investigation.
