Add CQL and OZ coloration for cassandra DB to nano.

Hello nano community,

I'm a master student and I have to make an open source contribution.  I have been using nano always since I have started using linux (6 years ago). I had fun to modify nanorc configuration files to make personalized things with the editor. I would want to integrate a complete colorization for two languages : Cassandra Query Language (cql) and Mozart Programming Language (OZ). I start to use CQL for my cloud computing course and I use Mozart2 system for my thesis. Nano is very useful because I use both system inside docker containers and nano avoids me to configure a whole X11 forwarding or passing by volumes to display files.

I'm open and I can work on other extension more interesting for you.

Hoping it interestes you,
Thank you for your time,
Best regards,
