Enable pagination of hybrid results

Simple fix to enable pagination of hybrid results, based on the existing code for pagination of transformed results:

- Added new TransformedFinder::createHybridPaginatorAdapter() method to get a paginator for hybrid results
- Added new HybridPaginatorAdapter.php based on TransformedPaginatorAdapter.php, but which uses HybridPartialResults instead of TransformedPartialResults
- Added new HybridPartialResults.php based on TransformedPartialResults.php, but which calls hybridTransform() instead of transform()
