Add an entry query parameter to filter by author count

[MoritzLost]

I need a query for all entries that have more than one author. As far as I can tell, that's only possible with a custom expression at the moment. It would be useful to have a query method on EntryQuery objects to allow filtering by author count.

For example:

// Only entries with 3 authors
$entryQuery->authorCount(3);

// Entries with 2 or more authors
$entryQuery->authorCount('>= 2')

// Entries with exactly 2 or 5 authors 
$entryQuery->authorCount([2, 5]);

Probably a few more cases I'm forgetting about, and I'm also not sure about the syntax. But something like this would be handy.

We can consider this, but in the meantime, you could create a generated field that stores the count, and query against that.

@brandonkelly Thanks for the suggestion! Yes, either a generated field or a custom DB expression. But would be useful to have as a query method for convenience.
