introduce suggested fixes for potentially unsafe or undesired fixes

[ajafff]

Some fixes may break the code but actually reveal errors, e.g. #186.
Then there are fixes that disguise an actual problem, e.g. #181 or #203. These are better fixed manually by the developer.
And then there are fixes that you don't want to happen automatically in your IDE if you use autofix-on-save, e.g. no-debugger.

This proposes adding a new category of fixes that may advertised in IDEs and other integrations. These fixes will not be automatically fixed with --fix.

TBD

• What does the API look like?
  • introduce a Failure class that has setters for regular fixes and suggested fixes?
  • introduce a Fix class with a category field
    • addFailure would then accept any number of fixes as variadic argument.
    • allows a failure to suggest different fixes for the same issue
• Each Fix needs a name/description so the user knows what it does
• Add CLI option to automatically apply all suggested fixes?
• How does this work with baseline testing?
