---------------------------------------------------------------
Here is my patch for this ticket. Aiming to handle not decodable fields
carefully.
- {{RetrieveFieldsOptimizer}} will only use DV for fields that are decodable.
- {{SolrDocumentFetcher}} will handle decoding DV more carefully. If there are
an Exception in decode a DV, it will fall-back on using stored value instead.

> Right now, Solr does not know how to decode DV value of
> LatLonPointSpatialField. Therefore, Solr will hit NPE when trying to do that,
> for example:
> - when fl contains a spatial field and it is DV + not stored
> - when fl only contains DV fields and any of them is a spatial field ( stored
> + DV ). Because SOLR-8344 will always use values from DV fields. This seems a
> common case.
