Highlights

This is a fairly minor release, primarily bugfixes and dialect improvements.

For python API users, there's the addition of a public method on the `FluffConfig`
object allowing the construction of a config object from multiple strings to
mimic the effect of nested config files in the CLI.

This release also includes a selection of internal refactoring and reorganisation
to support future development work.

This also sees the first contributions by [ShubhamJagtap2000](https://github.com/ShubhamJagtap2000)
& [kang8](https://github.com/kang8), particularly notable in that both were
contributions to SQLFluff documentation! 🎉🎉🏆🎉🎉
