v0.29.4

• Allow outputting BAM files via --out-bam
• Updated QC (counts for each tag for each error distance outputted in summary file).
• Updated the column names to use singular words (i.e. tag instead of tags, group instead of groups, etc. -- though the plural version still works for backwards compatibility purposes).
• Allow keep:, keep-grp:, remove:, remove-grp: to be supplied directly in config file
• --keep-r1-r2 option to allow demultiplexing to be outputted using _R1.fastq and _R2.fastq suffixes (rather than _0.fastq and _1.fastq)
• Implemented a --min-delta
