[issue14156] argparse.FileType for '-' doesn't work for a mode of 'rb'

It's been sometime since I looked at this issue.  

The main sticking point is passing unittests, and ensuring that there are no backward compatibility issues.

But, since FileType is a standalone class, anyone could put a corrected version in their own workspace without modifying their stock version.  The 'type' parameter is designed for this kind of flexibility - it accepts any callable, whether a function, or a class with a __call__ method.
