Add wrapper functions for getAllFilesFromDir with named parameters

[lukfor]

Hi all,

First of all, thank you for collecting all the nice snippets in one plugin. I really appreciate your effort! I believe having an independent plugin separate from the nf-test releases helps to incorporate changes more quickly.

I noticed that the Hackathon has its own nf-test plugin group. That’s wonderful to hear! 🚀

This PR adds a wrapper to the getAllFilesFromDir function and utilizes named parameters (a concept frequently used in Nextflow). I think this could serve as a good boilerplate to demonstrate how this approach can be implemented. It improves code readability and allows for the inclusion of additional optional parameters with default values, without making the method signature unreadable.

Example:

def stable_name  = getAllFilesFromDir(params.outdir, ignore: ['pipeline_info/execution_*.{html,txt}'])
def stable_content = getAllFilesFromDir(params.outdir, includeDir: false, ignore: ['pipeline_info/execution_*.{html,txt}'], ignoreFile: 'tests/getAllFilesFromDir/.nftignore')
assert snapshot(
  // Only snapshot name
  stable_name*.name,
  // Snapshot content
  stable_content
).match()

//with default params and relative
println(getAllFilesFromDir(params.outdir))
println(getAllFilesFromDir(params.outdir, relative: true))

I also included a relative option to combine it with getRelativePath(..).

Hope this helps and thanks guys! 🚀🙏
