Release v1.3.0

Added

• Added --keep flag to prevent files from being deleted from the output directory. The --keep (alias: -k) causes batch-transcode-video to never delete any output files, no matter what happens, even if the encoding task fails for the corresponding input file. If you use this option, input files that fail to encode correctly, or finish encoding, will not be deleted from the output folder. Subsequent runs, with or without using the --diff option, will not reprocess the failed input files, unless the corresponding output files are manually deleted.
