Fixed issue with passing inverted bits keyword arguments

[bmeisels]

When a user passes in black_bits_inverted or color_bits_inverted the IL0373 initializer will pass the keyword argument twice to the displayio.EPaperDisplay initializer rwhich raises an exception ('TypeError: extra keyword arguments given').

The fix is to swap dict.get for dict.pop

@tannewt i just noticed that if swap_rams is true that color_bits_inverted / black_bits_inverted are referring to the wrong keyword args. I will add a fix for that too.

I think that's on purpose because they're being swapped.

[bmeisels]

I thought the swap was referring to the actual commands and not to the inverted option.
If i am wrong though ill remove the last commit.

Let's see what @tannewt says.

Thanks for the fix! I agree that swapping black and color ram args with swap_rams is the right approach. The two examples that use swap_rams don't set either so it is safe to change.

Would you mind adding parameter comments into the class comment? I should have done it when I added the driver.

[bmeisels]

@tannewt I added documentation.
I think it would be a good idea to eventually make the kwargs explicit.

[tannewt]

Thanks for the doc! One question about it.

Ok, great! Would you mind filing an issue on CircuitPython to support R? It should be easy to add.
