1.8.1

Update conda package

1.4.4

• Create bioconda package

• Support custom genomes. Provide a path to indexed fasta file with -g:

targqc *.bam --bed target.bed -o results -g /path/to/some_genome.fa

When running from BAMs, only the .fai index is used, and the fasta file itself can be non-existent.
When running from fastq, bwa indexes are also required.

• Add script to build Venn diagram for a set of BED files:

bed_venn.py *.bed -o res_dir
