Hi Guix,

attached is a patch to add a couple of transcriptome analysis scripts.
I had to use the git downloader because the releases are unusable: they
are really old and only contain the scripts but no longer the setup.py
script.

The git clone also isn't that nice; I had to delete some clutter after
unpacking and fix the permissions on the python scripts or else
installation would fail.

About the name: "pbtranscript(-tofu)" is the correct name, whereas
"cDNA_primer" is not, even though the repository is named "cDNA_primer".

This patch depends on three other packages:

- python2-pbcore:

- python2-h5py:

- python2-bx-python:
