Title: SB implement required voters

Implements the "required" config option described in the README.
Can either be a static array of usernames or a proc that is passed the raw data from the incoming webhook and returns an array of usernames.
When the array is non-empty, all of the specified users must vote +1 (in addition to sum of +1 votes exceeding threshold) in order for the PR to be auto-merged.
