Find one file using the Bucket class

[christeredvartsen]

MongoDB\GridFS\Bucket::find() forwards to MongoDB\GridFS\CollectionWrapper::findFiles() which in turn forwards to MongoDB\Collection::find(). This method creates a MongoDB\Operation\Find command. The MongoDB\Collection class also has a findOne method which uses the MongoDB\Operation\FindOne command, which is not reachable using MongoDB\GridFS\Bucket or MongoDB\GridFS\CollectionWrapper in the same manner.

It would be nice to have a MongoDB\Bucket::findOne() method as well (I guess one can accomplish the same by specifying ['limit' => 1] as an option to the find method, but still...).

If this is something you would like to include I'd be happy to send a pull request including necessary tests and documentation.

I opened PHPLIB-238 to track this. An implementation is sitting in #290.
