Working with audio worklets

1. Noise worklet: a 'hello world' audio worklet generating a noise source
2. async await format: the Noise worklet, but now implemented using async await instead of a promise then.
3. Multiple inputs: showing how one can have audio worklet nodes with multiple inputs, demonstrated with an audio worklet that finds the sample with maximum amplitude from all channels of all inputs .
4. PanX: an audio worklet that pans audio between any number of loudspeakers. This demonstrates use of inputs, outputs and options for an audio worklet.
5. Gain worklet: A simple gain node implemented as an audio worklet, to show how audio worklets handle audio parameters.
6. Smoothing Filter worklet: to show how an audio worklet stores internal variables, we implemented a smoothing filter. The audio worklet keeps track of the previous sample even though it reads in audio block by block.
7. First order filter options: first order high pass and low pass filters. They are implemented in a single audio worklet, with processorOptions specified to set the filter type.
8. First order filter messages: first order high pass and low pass filters. They are implemented in a single audio worklet, with the message port used to set or change the filter type.
