Houdini - Premiere Timecode list parser

## This should be pasted into the Python node in SOPs
## Add two interface parameters - "txt" of type File and "framerate" of type int
## This script is parsing a marker list from Adobe Premiere Pro. It should be saved as CSV file and next resaved with UTF-8
## On the output it creates a number of points equal to number of markers.
## Each point has attribute start as marker start (in frames) and end as marker end (in frames)
