laentropia 7ad4eba123 fix/refactor: Modified evaluate and changed it to evaluate_tree
So i did what the last commit said, also fixed parse_expr because it was
still using malloc for allocating new nodes so i made it use arena_alloc
like it should, did the very first tests so it's all good, i think is
readdy to merge.
