One-off custom reviews

If you request Neo review a PR using a comment, you can customise the criteria Neo reviews with. For example:

@neo this PR according to these rules: 1) …
@neo review this PR according to the Google C++ Style Guidelines https://google.github.io/styleguide/csharp-style.html
@neo review this PR for incorrect locking in the concurrency code

When Neo is reviewing like this, it won’t review in the default ways it does as described in Add as a reviewer.

After it has finished, Neo will tell you what it has reviewed the PR for, and what passed and failed.
