Feature: `.sauced.yaml` could support an ignore feature

[bdougie]

Suggested solution

Per feedback from a maintainer, there are files and folders that do not need a codeowner. My suggestion is adding an ignore option to the .sauced.yaml.

// .sauced.yaml

ignore: 
  - package.json
  - /markdown-things

The optional section could be an ignore or include section, but not both. The user can decide depending on how large the difference is between what to ignore, or what to include.
