lib.FileContext.open(): Add method

Browse source 
Add an async open() method which should allow to do what __init__() couldn't, because it's not async, and to match the already existing .close(). It's called by __aenter__() __aexit__() if the FileContext is instantiated as context manager, or at will when the user finds it a good idea.
