srge chunk

The 'srge' chunk is Surge XT's own versioned metadata chunk inside WAV files, telling its importer the frame layout the same way Serum's 'clm ' chunk does.

The payload carries a small version number and a frame-length value. Surge XT writes 'srge' into the wavetable WAVs it exports — and its 'srgo' variant into sample exports — while still honoring 'clm ' on the way in. Chunks like these are the quiet reason packed-WAV wavetables travel well: the audio alone is just one long waveform until metadata says where the frames fall.
