py-cutadapt: updated to 3.4

v3.4 (2021-03-30)
-----------------
* :issue:`481`: An experimental single-file Windows executable of Cutadapt
  is `available for download on the GitHub "releases"
  page <https://github.com/marcelm/cutadapt/releases>`_.
* :issue:`517`: Report correct sequence in info file if read was reverse complemented
* :issue:`517`: Added a column to the info file that shows whether the read was
  reverse-complemented (if ``--revcomp`` was used)
* :issue:`320`: Fix (again) "Too many open files" when demultiplexing

Log message:
py-cutadapt: updated to 3.3

v3.3:
* :issue:`504`: Fix a crash on Windows.
* :issue:`490`: When ``--rename`` is used with ``--revcomp``, disable adding the
  ``rc`` suffix to reads that were reverse-complemented.
* Also, there is now a ``{rc}` template variable for the ``--rename`` option, which
  is replaced with "rc" if the read was reverse-complemented (and the \ 
empty string if not).
* :issue:`512`: Fix issue :issue:`128` once more (the “Reads written” figure \ 
in the report
  incorrectly included both trimmed and untrimmed reads if \ 
``--untrimmed-output`` was used).
* :issue:`515`: The report is now send to stderr if any output file is
  written to stdout

Cutadapt finds and removes adapter sequences, primers, poly-A tails and other
types of unwanted sequence from your high-throughput sequencing reads.
