Pandoc in pip and conda. Contents:
- conda-forge/pandoc feedstock backup,
- pypi stub that prevents name clash with conda-forge/pandoc is not needed as there is already a useless pandoc package on pypi (better use panflute instead),
- pypi py-pandoc package (+ workaround for pip on Anaconda being not aware of pure conda packages),
- conda-forge/py-pandoc feedstock backup.
