feat(clear-text-reporter): Adds a "skipFull" option

[sebiniemann]

Resolves #4690

I wasn't sure where you wanted these changes, so I've tried to be minimally invasive while covering everything mentioned in the issue:

• Excluding files with a 100% score
• Skipping "All files"
• Omitting the entire table if all files achieve a 100% score

Hopefully all pipeline tests and validations proceed smoothly, but we'll see how it goes :)
