Use Bio.trie for barcode matching

A bit faster and more transparent than the previous regex-based method.
Also allows for samples to be delineated by a combination of barcode and
primer, when multiple loci are amplified.

Tested against previously filtered data: no external changes introduced.
backtrans-align: Error on extra aa/codons

Raise an error (rather than allowing StopIteration to propagate) when
the number of amino acids doesn't match the number of codons in an
alignment.

Previously stopped silently prior to processing all sequences.
