handle CantDeserializeException raised from deserialize method
Added new construct :class:`.api.CantDeserializeException` which can be
raised by user-defined deserializer functions which would be passed to
:paramref:`.CacheRegion.deserializer`, to indicate a cache value that can't
be deserialized and therefore should be regenerated. This can allow an
application that's been updated to gracefully re-cache old items that were
persisted from a previous version of the application. Pull request courtesy
Simon Hewitt.
