The import('fs') returned a Promise that was never awaited, causing
the concat manifest file to be written asynchronously after ffmpeg
tried to read it. This would result in an empty concat file and
ffmpeg failure.

The parseMultipart function was trying to .split() a Buffer as if it were a string, causing 'body.split is not a function' errors on the transcribe endpoint. Also fix the boundary detection to properly handle binary audio data using Buffer.indexOf() instead of string split. Signed-off-by: Pip <pip@zerologic.com>
