seqcluster needs ViennaRNA

package seqcluster

   https://github.com/lpantano/seqcluster/archive/1824d37.tar.gz

   https://salsa.debian.org/med-team/python-seqcluster

      Some nitty-gritty was going on there wrt Python3 transition

      and an upcoming new release. Needs another review and

      likely some communication with upstream.

         Steffen addresses this.

      The Python3 transition seems fine now. Weird, though,

      the test takes too long / something hangs.

      When grepping for "conda install":

       ./doc/source/installation.rst:    ~/install/seqcluster/anaconda/conda install seqcluster seqbuster bedtools samtools pip nose numpy scipy pandas pyvcf -c bioconda

       ./Dockerfile:     conda install --yes -c conda-forge -c bioconda scipy seqcluster bedtools samtools pip nose setuptools -q && \

       ./.travis.yml:- conda install --yes -c conda-forge -c bioconda memory_profiler openjdk pysam pybedtools pandas numpy biopython progressbar2 pyyaml bedtools samtools mirtop viennarna -q

      so, for some successful testing it seems like we need viennarna, still. That is not yet in the distribution. If truly dependending on it then bcbio ends up in contrib.

package viennarna

    https://github.com/ViennaRNA/ViennaRNA

    https://salsa.debian.org/med-team/vienna-rna/blob/master/debian/changelog

       No idea about where exactly we stand with this.

       The package now has a custom license file - redistributable but non-free.

    Needed for testing seqcluster.
