Reverse complement config option seems incompatible with tags from files #43

When you specify tags in files, turning on reverse complementing appears to try and reverse complement the filename, instead of the tag sequences inside the file resulting in:

Error: Sequence #1: "cell.barcodes" contains a non-ATCG character

The workaround is to append all reverse complemented tag sequences into the input files.

However, I was hoping to only have my tag sequences files be the canonical sequences and take advantage of the --revcomp setting.
