libsndfile also can extract loop points from a variety of formats. The relevant
code for wav is here

Thanks, Dan!
They must be embedded in the "Marker Chunk" in AIFF and in the "Cue Point
Chunk" in the WAV format.
This gives me a further idea for searching on.
Yes, loops are usually defined as "Loop Start" and "Loop End" cues,
Hmm, or maybe they are usually defined in the "smpl" chunk, I don't remember...
But here's the code to get loop data from a wav file in radium:
https://github.com/kmatheussen/radium/blob/master/audio/Sampler_plugin_wav_parse.c#L253
First it checks if there is a loop in the "smpl" chunk. If there isn't
loop data there, it checks for "Loop Start" and "Loop End" cues.
