Python runtime: bytes comprehension

[arekbulski]

I am too busy with other work so I am leaving this work item. I am implementing ProcessXor in Construct and found that this code

        if PY2:
            return bytes(bytearray(v ^ key for v in bytearray(data)))
        else:
            return bytes(v ^ key for v in data)

could easily be

            return bytes(v ^ key for v in data)

because bytes([1,2,3]) works on Python 2 as well.

@dgladkov did some benchmarks previously: kaitai-io/kaitai_struct_python_runtime#8 and claimed that it was the optimal solution.

Okay, then I will withdraw this and focus on more important work.
