create colorful video barcodes -- shared library

 nordlicht converts video files into colorful barcodes. It's heavily inspired
 by the "moviebarcode" tumblr. It takes the video's frames in regular
 intervals, scales them to 1px width, and appends them. The resulting barcodes
 can be integrated into video players for simplified navigation.
 .
 This package contains the library which encapsulates the video barcode
 functionality.
