/**
* Interface that defines API for simple extensions that can provide additional deserializers
* for deserializer Map keys of various types, from JSON property names.
* Access is by a single callback method; instance is to either return
* a configured {@link KeyDeserializer} for specified type, or null to indicate that it
* does not support handling of the type. In latter case, further calls can be made
* for other providers; in former case returned key deserializer is used for handling of
* key instances of specified type.
