Fancy ANSI formatting for lint and format log outputs

[ewels]

Nicer output from the new nextflow format and nextflow lint commands. @bentsherman you will probably want to clean up my crappy Groovy code, but I'm happy with the outputs now.

TODO:

• Replicate the .gitignore exclusions to format
• Refactor code to avoid duplication
• @bentsherman to clean up my crappy groovy code
• [Maybe]: Improve .gitignore code to work when launching from anywhere in the project tree

Added some more functionality:

• Ability to output the lint results in different formats (full, concise, summary, json)
• Lint now throws an exception (and so exits with a non-zero error code) if any errors were found
• Ability to -exclude one or more files / dirs / glob patterns
• Parsing and use of a .gitignore file if present

The .gitignore stuff is only in lint for now - it should be in both but I don't want to just copy it over, as there is more and more duplication between the two CLI files now. But I'm not really sure where I should put this shared code?

Wonder if we can set up GitHub actions to use the JSON output to spit out error messages for inline PR notes about lint errors 👀

I read somewhere that it's only possible to do 10 at a time from GitHub Actions (GitHub apps more), many links seem outdated, so may need a bit of testing to see how viable it is.

• Remove .gitignore logic for now until we decide on an overall strategy (see Repo config file for lint / format #5934)
• Use "error listener" interface to separate output formats from core linting logic
• Re-use the ANSI error listener in the script loader
• Move file exclusion checker into nf-lang (it will be re-used by the language server)
