Release v1.1.0

Changes to get_plasmid_inserts.py:

• only fastq is output by default now; table output requires --table option
• fixed bug which didn't concatenate reads for fastq output
• default distance changed from 5% to 10% of flanking sequence length
• --no-empty removes empty inserts from both fastq and table output now, not just table

Changes to utils.py:

• is_DNA function now doesn't accept N as a valid base. It doesn't make sense to accept N bases in flanking regions for get_plasmid_inserts or in barcodes for demux_inline_bc since they won't be matched as might be expected (won't match any base except N rather than matching any base).

Added demux_inline_bc.py script for demultiplexing fastq files with barcodes within reads.

Updated testing to use pytest instead of unittest.
