Support Python 3.8 - Githubissues

Numba 0.46 doesn't support Python 3.8. See for example https://github.com/numba/numba/issues/4712.

Example of failed unit test:

As soon as a py3.8-version compatible Numba version (0.47) is available:

[X] Set the minimum Numba version in setup.py and the Bioconda recipe.
[X] Enable unit tests for Python 3.8 in .travis.yml.
[X] Include the Python 3.8 badge in the README and the documentation homepage.
