Consider chipping off the Cylc Pygments lexer into another repo

[oliver-sanders]

This repo was created to assist with the development of the Cylc and Rose documentation, it has a GPL license as a result.

However, the Cylc Pygments lexer may be of interest to other projects, e.g. those wishing to document Cylc workflows. To facilitate such uses a more permissive license would be appropriate (e.g. we use BSD for cylc-textmate-grammar).

We could potentially consider chipping off the lexer into its own repo ( 🤦 ), or even potentially relicensing this entire repo (the only thing stopping us is the Cylc autodocumenter which imports Cylc libraries and could be moved into cylc-doc).

This like might need expanding to support other *.cylc files. Otherwise the lexer itself seems independent.
