* Since we only care for actual waves, to get its name we need to find which cue uses our wave.
* Multiple cues can use the same wave (meaning multiple names), and one cue may use multiple waves.
* There is no easy way to map cue name <> wave name so basically we parse the whole thing.
*
* .acb are created in CRI Atom Craft, where user defines N Cues with CueName each, then link somehow
* to a Waveform (.awb=streamed or memory .acb=internal, data 'material' encoded in some format),
* depending on reference types. Typical links are:
* - CueName > Cue > Waveform (type 1)
* - CueName > Cue > Synth > Waveform (type 2)
* - CueName > Cue > Sequence > Track > Command > Synth > Waveform (type 3, <=v1.27)
* - CueName > Cue > Sequence > Track > Command > Synth > Synth > Waveform (type 3, <=v1.27)
* - CueName > Cue > Sequence > Track > TrackEvent > Command > Synth > Waveform (type 3, >=v1.28)
* - CueName > Cue > Sequence > Track > TrackEvent > Command > Synth > Synth > Waveform (type 3, >=v1.28)
* - CueName > Cue > Sequence > Track > TrackEvent > Command > Sequence > (...) > Synth > Waveform (type 3, >=v1.28)
* - CueName > Cue > Block > Track > Command > Synth > Synth > Waveform (type 8)
* - others should be possible
* Atom Craft may only target certain .acb versions so some links are later removed
* Not all cues to point to Waveforms, some are just config events/commands.
* .acb link to .awb by name (loaded manually), though they have a checksum/hash/header to validate.
