Remove LeftStickAsAnalog, RightStickAsAnalog, DPadAsAnalog from simulated input

As mentioned here it's unclear what these buttons do, but they're not binary so don't represent a button press simulation. Therefor we should remove them:

[...] And as for these buttons: LeftStickAsAnalog, RightStickAsAnalog, DPadAsAnalog. I too have no idea what they represent. I left them in, because I thought they might be useful to someone who knows what they do. The package used internally SimWinInput exposes them.
However looking at that code of that package again, it seems it doesn't mark those buttons as 'binary' (pressed or not), so I guess I should remove them from the options. I'll make an issue for that right away!

Additionally it would be nice to find out what they do actually represent
