MariaDB CREATE+READ connector

MariaDB RDBMS is enabled by Python's mariadb package. However, on Debian-based distros, this package requires APT package libmariadb-dev to be installed ; if it is missing, or badly configured, or only available at a not-that-old version, pip install mariadb installation fails.

So, if pyheimdall would have a hard dependency on mariadb, what many users would do would ressemble this :

1. pip install pyheimdall

   Installation fails because mariadb installation fails ;
2. understand mariadb red error message, then try ...

   apt-get install libmariadb-dev

   ... which in most cases fails because the version that is available in their distro is too old ;
3. STFW for where to find a recent version of libmariadb-dev, find the answer, accept the risk to use its non-standard repo, then :

   curl -LsS https://r.mariadb.com/downloads/mariadb_repo_setup | sudo bash
   apt-get update
   apt-get upgrade
   apt-get install libmariadb-dev

4. Finally reinstall our package:

   pip install pyheimdall

Honestly, this is such a PITA. No non-tech user would endure such an "ordeal".
This means nobody sane would install pyheimdall, and all this would be because of an optional feature, because not everyone is interested by MariaDB support.
