open() does not allow binary IO

[polyfloyd]

Reading files opened by open("rb") returns a TextIOWrapper instead of something that allows binary IO. The emulator returns an instance of FileIO which seems to work just fine.

with open("somefile", "rb") as f:
    print(type(f)) # TextIOWrapper, expected be FileIO (or BufferedReader according to the Python documentation)

As a consequence, f.read() returns a str instead of bytes.

hmm.. it should return FileIO.. diving into it..

probably fixed in pull-request #166

@polyfloyd can you verify if current master solves this issue for you?

[polyfloyd]

@annejan Yeah, it has.
