A function to attempt identifier remapping from the name found under classKey.
If this function is provided, then when the classKey is found, this function
will attempt to remap the value. This function should return either the fully
qualified class name or null. Returned non-null values indicate that the
remapping has succeeded. A null value will indicate the mapping has failed
and the original value will be used in the object factory.
This is particularly useful when input JSON has not originated from D.
