Can not detect the initial state of half step rotary encoder correctly

[scarrrr316]

The problem is that the code is unable to detect the initial state correctly, causing fail detection of the first half-step.

The way I solved the problem was to add this line:

self._process_rotary_pins(None)

to the end of the __init__ function of the RotaryIRQ class.

I don't know how it works, but it works.
