Update to newer versions of crates.

See merge request !3

Build and deploy wheels for Python 3.9

See merge request !4

I don't know why the CI refuses to properly name the wheel for 0.3.1.

See job https://gitlab.merchise.org/mercurio-2018/python-comrak/-/jobs/147990
and you'll notice it's trying to upload past-releases:

     dist/python_comrak-0.3.0-cp38-cp38-manylinux2010_x86_64.whl (1.5 MB)

This is either a bug or feature of gitlab which I rather avoid.

I was lazy copying from travertine.

Expose pulldown_cmark as well which is faster than comrak.

See merge request !2

There are differences in output because pulldown_cmark doesn't support the
whole specification and the supports a single extension.  I still prefer
comrak because it filters tags.

Add Gitlab CI standard pipeline.

See merge request !1

These mostly has to do with our choice of having auto-links and tag-filters on
by default (actually we don't give the option).

After all, we're only exposing comrak::markdown_to_html without any options.
