Site 1.3.0: advanced waveforms published by us, 1.0.1

Advanced waveforms is based on arnoldasr's rgb_waveform and now updated
and published by us (cards, docs, builder, credits). 1.0.1 takes rekordbox's
colours also when they are a little short. The generator masks only the
asset blob itself, so code of ours after it goes as data.
