Enhance WOH image to support extraction of multiple images using multiple encoding profiles from multiple sources
The goal of this issue is to extend WOH image so that it additionally supports:
Extraction of multiple positions
Encoding using multiple encoding profiles
Add support for relative positions (relative to duration of source track)
With this extension, it will be possible to use a single instance of WOH image to extract images from multiple source flavours at multiple positions (both absolute or relative) and encode them using different encoding profiles ("qualities").
