Add "--fix" feature

[caitlinelfring]

Most linters have the ability to automatically fix any violations that are found. Some examples:

• eslint
• gofmt
• golangci-lint
• shfmt

This feature will also allow woke to take advantage of GitHub suggestions using something like reviewdog/action-suggester

A caveat with this feature is this should be a "best effort" fix and doesn't guarantee that the fixes it makes will produce functioning code as renaming variables/functions/methods/classes can have far-ranging implications and therefore, using this feature shouldn't be done with blind trust.

Features

• Opt-in only (disabled by default)
• Uses the first "alternative" for replacement
• Should be able to write fixes to files as well as write the diff to stdout
  • Something similar to gofmt -w

-w
  Do not print reformatted sources to standard output.
  If a file's formatting is different from gofmt's, overwrite it
  with gofmt's version. If an error occurred during overwriting,
  the original file is restored from an automatic backup.

• Should work with reviewdog/action-suggester
• Output a warning to stderr about the risks of using this feature.
