Support for Pull up / Pull down resistors

[user2684]

It would be great (if not too complex) to add support for the RPi.GPIO pull_up_down argument of setup() since it is very common to have pull up/down set when reading an input.
I've tried the trick to output e.g. HIGH before reading but I correctly got an error saying the pin is supposed to be an input not an output.
Alternatively, I'd recommend adding the pull_up_down option anyway and just print out a warning saying it is not implemented so to ensure compatibility with existing code. A similar approach can be used for bouncetime and other optional parameters in this way the code will be fully compatible even if the functionality is not implemented.

Thanks

Yes, pull-up and pull-down arguments are on the radar, but at present I'm not sure if it is fully supported by the GPIOs on the Orange Pi Zero. But I like your idea of accepting them regardless and displaying a warning.

Bouncetime should be easier to support, but in the meantime I'll also add the params and emit some warnings.

Version 0.2.4 adds compatibility (but no functionality other than an emitted warning) for pull-up/down resistors and bouncetime.

Good job, this will for sure help me in making the code cleaner without too many if based on the platform :-) (https://sourceforge.net/p/my-house/tickets/216/)
