elPrep Binaries

elPrep binaries compiled with Go.1.11.5.

Bug fix:

There was an issue when the --replace-reference-sequences option was used with the elprep sfm command, which under certain circumstances may have resulted in improperly sorted results. This has been fixed in elprep version 4.1.1. Thanks a lot to Geert Vandeweyer for reporting this issue.

Additional fixes:
- The --replace-reference-sequences option incorrectly removed unmapped reads. This has been fixed in version 4.1.1 and does not happen anymore.
- The --contig-group-size option has been deprecated for the elprep merge command. The elprep sfm and elprep split command still support it. The elprep split command now works correctly without knowing the --contig-group-size that was passed to the corresponding elprep split command.
- The BGZFWriter panicked when a Write happens after a Close because of sending data to a closed Go channel. This has been changed into a proper error return value.
