Add simple Avro transformers
Unsophisticated Avro transformers for `SpecificRecord` implementations. * * Fix DSL Factory - transformer was changed to `<? extends GenericContainer>`; change the DSL to match * * Restore test log4j * * Revert to supporting only SpecificRecord * * Fix assert * * Add multi-type deserialization with fluent API * Polishing for PR comments * * Remove type mappings; Exxpression now returns the type (or class name) * Cache types created from class names * Add type header in "toAvro" transformer * * Remove the type cache (already handled by the class loader) * * Don't convert the class to String in the "toAvro" transformer
