Arriba v2.4.0

• new utility script to annotate exon numbers
• compatibility with Illumina's Dragen aligner (see notes in manual about supported aligners)
• retained fraction of protein domain was often overestimated as 100%
• better agreement of transcripts between Arriba's output file and the visualizations produced by draw_fusions.R by making --transcriptSelection=provided the default
• better matching of structural variant breakpoints to fusion breakpoints when parameter -d is used
• VCF files generated by scripts/convert_fusions_to_vcf.sh are now compatible with bcftools
• mildly improved filtering
