Remove ligation artifacts

The remove ligation artifacts functionality in the LightSpeed tools is designed to eliminate reads that likely originate from ligation artifacts introduced during library preparation. This functionality is identical to that of the tool Remove Ligation Artifacts, where it is described in detail.
