Add documentation for `flake8 --extend-ignore`

See merge request pycqa/flake8!258

Most of the problems with our logic were due to not having the same
logic as our exclude parameter. This refactors that out into a separate
function so we can confidently achieve that.

These show that there were some subtle bugs in how we were matching
things and that there are bugs that need to be fixed.

Also highlight the behavioral differences between `flake --ignore` and
`flake --extend-ignore`.

This adds support for rules that ignore violation codes on a per-file
basis. This takes a similar functional approach to
https://github.com/snoack/flake8-per-file-ignores which allows for glob
patterns like the `--exclude` option.

Closes #156
