Possible bug in moonshine-web prevBuffers management.

[ShaheedHaque]

In moonshine-web, the content of prevBuffers is effectively consumed around

transformers.js-examples/moonshine-web/src/worker.js

Line 140 in 38a883d

for (const prev of prevBuffers) {

but prevBuffers itself does not seem to be consumed. Changing the reset() function to add this line is a possible fix:

const reset = (offset = 0) => {
...
  BUFFER.fill(0, offset);
  bufferPointer = offset;
  isRecording = false;
  postSpeechSamples = 0;
  prevBuffers = [];                  <<<<<< added line
};
