BPF file format doesn't match what expected of `revcor` project

[jjau]

The revcor repo offers the possibility to quickly build reverse correlation experiments with files generated by cleese. However, it expect bpf files to

• have exactly the same name as the stimulus file, with a txt extension (ex. sound001.wav and sound001.txt)
• that columns of the bpf are labeled with a header and comma separated (ex. time, pitch\n 0, 150)

That format isn't enforced in how PhaseVocoder saves bpf files in batch mode (default right now is sound001_bpf.txt, no header and Tab-separated values). This should be fixed either hard in code, or via the config file (see e.g. user-specified extensions for Mediapipe dfm)

[update] on it. have modified the file extension, and FaceWarp header. Need to add header in PhaseVocoder.
