EmscriptenAudioWorkletNodeCreateOptions missing couple of options

[RReverser]

EmscriptenAudioWorkletNodeCreateOptions has bindings for options of AudioWorkletNode itself, but AudioWorkletNode inherits from AudioNode which also accepts:

• channelCount
• channelCountMode
• channelInterpretation

Being able to configure those is useful when you e.g. care about only one input audio channel and don't want the Web Audio system to produce garbage Float32Arrays for other channels that you're going to ignore anyway.

Indeed, these are fields that I missed in the initial implementation. Fortunately the options are passed as a struct, so it should be possible to expand to add these. I can't make a promise that I would be able to get to adding these in a moment, as I am currently looking to fix other things, so if you want to take a stab at an implementation meanwhile, that would be cool.

Kind of the same, it should be a very simple fix just not getting around to it at the moment, so at least opened for tracking.
