Generate from another sample

Set outname to be the base filename for the output file (stored to the .generated directory)

Set c2file to be the filename of the Codec2 encoded file containing the seed

Set seed_start_index to be one of: "random", the frame number, or more conveniently the number of seconds into the audio (for example "27s")

The generator takes several minutes to complete. It will not run if the outname.wav file already exists.

The first 5 seconds of audio are the original seed data. The remaining audio is generated from the network model specified.
