Change yaml parser to org.snakeyaml:snakeyaml-engine

[aminadinari19]

Hi! There is a new version of snakeyaml (2.0) which seems to be free of vulnerabilities. Do you plan to upgrade to that?

[thomasdarimont]

How about simply removing the dependency to snakeyaml?

The regex format file regexes.yaml is quite simple and could be parsed by a small handwritten parser that just turns the yaml into a ``Map<String,List<Map<String,String>>>`

I think it is even better to remove the need to have any YAML parsing at runtime.

So I have opened a PR for that: #83

This will also address #68

At first I was hoping the snakeyaml maintainers would address the issue in their library but I read through their issue/conversation and, apparently, it's very controversial...

I'll check out snakeyaml-engine and see how complicated it is to swap over.

I'd prefer to avoid writing a custom yaml parser

[jmini]

I have opened a PR to update to version 2.0 of the regular snakeyaml: #82

I agree with the discussion here, snakeyaml-engine might be a good fit for this library:

I'm pleased to announce version 1.6.1 has been released to Maven Central and the security vulnerability has been addressed.
