GTP Ligand and Target files have a extra commented row above table that needs to be skipped

example:
## GtoPdb Version: 2022.2 - published: 2022-06-09

This GtoP step is falling because it is expecting the header row instead of this commented line. I have removed the header line to get it to work with v82 but needs to be fixed for v83
