Title: waveform generation updates & fixes

* follow suit and don't impose max width/height
* bin-size: interpolate samples per x-pixel (fix issue with missing samples at end of wave-form for short files)
* fix buffer allocation crash (when merging multiple channels) and also free buffer
* allow to use audio-frames as x-unit
