MapIterator is not usable with graphqlite

[Kharhamel]

Since we can return ResultIterators to graphqlite, we should be able to return mapIterators too since they are specific resultIterators.

Not sure what you mean.

MapIterator is an iterator, so you need to tell GraphQLite the exact type in the @return annotation, but this should work.

Something like this should work:

/**
 * @Query
 * @return MapIterator|string[]
 */
public function test(): MapIterator
