Add option to exclude (comment) blocks from formatting

[raszi]

Request

Implement a feature in cljfmt to exclude (comment) blocks from formatting. This is essential for those of us using these blocks for REPL-based development, as current formatting disrupts the workflow.

Suggested config

Allow specifying forms to exclude in the configuration, like:

:exclude [#"^comment"]

Impact

This addition would greatly aid developers who rely on specific formatting within (comment) blocks for efficient REPL interaction.

Thanks for your work on cljfmt!

Thanks for the suggestion. I think I'd prefer a boolean :ignore-comment-forms? as an option instead for this, as it lends itself more easily to a command-line switch: --ignore-comment-forms.

That works, but that is less flexible, I thought there would be other use cases for this.

The other option could be to introduce an --ignore-comment-forms option that will set the exclude config to comment, and if you want to have more fine-grained control, then you could set the exclude manually.

Of course, then the CLI options would divert a bit from the config. The third option would be to add both. :)

But maybe I am overthinking and ignoring comments would be enough.
