If the state miniaudio side of the device does not match the actual
state of the backend side of it, such as when the device is stopped but
the backend doesn't post a notification, attempting to stop the device
might result in a deadlock.

This is a just a quick workaround hack for the moment while a more
robust solution is figured out.

The SSE2 code paths for mono expansion introduced in Version 0.11.15
mixed up the parameters of `_mm_shuffle_ps()`, which in turn caused
adjacent PCM frames to be swapped in the channel-expanded output.

This is just a small project to experiment with a few API ideas. This
is not a replacement for miniaudio or anything so don't panic.

This applies only to duplex devices.

This unifies, as much as possible, the ScriptProcessorNode path with
the AudioWorklets path to avoid some code duplication, and to also make
the two paths more similar to each other to ease in maintenance.

  * Duplex mode now only creates a single AudioContext and AudioWorklet
  * Devices should now automatically start in response to a gesture

This adds the following APIs:

  * ma_sound_stop_with_fade_in_pcm_frames()
  * ma_sound_stop_with_fade_in_milliseconds()
  * ma_sound_set_stop_time_with_fade_in_pcm_frames()
  * ma_sound_set_stop_time_with_fade_in_milliseconds()

These functions will overwrite any existing fades. For the
set_stop_time variants, you specify the time that the sound will be put
into it's stopped state. The fade will start at stopTime - fadeLength.
If the fade length is greater than the stop time, the fade length will
be clamped.

This adds the following APIs:

  * ma_sound_set_fade_start_in_pcm_frames()
  * ma_sound_set_fade_start_in_milliseconds()

The sample format of a WAV file is not always being set which results
in get_data_format() returning ma_format_unknown.
