initial commit of simple bytecode translator
implement appendAll helper function
catch improper opcodes
initial commit of simple bytecode compiler
better errors
add translator test
remove reflect dependency

all opcodes now have the signature func([]byte) error, which removes the
need for reflection. The only downside to this is that it makes function
arguments less readable. I think the positives outweigh the negatives.
