By default, the `sndGes` function generates sound based on the 32 bytes at 0x00050. This means that in the default configuration those 32 bytes act
as sound registers. See the `sndGes` function for the meaning of those registers.
### export fn snd(sampleIndex: i32) -> f32
If the module exports a `snd` function, it is called 88200 times per second to provide PCM sample data for playback (44.1kHz stereo).
The `sampleIndex` will start at 0 and increments by 1 for each call. On even indices the function is expected to return a sample value for
