Description
Right now, Fast-Avro would fail fast during fast-class generation when encountering an unknown enum value, which is different from the vanilla Avro, which would fail the de-serialization when encountering an unknown enum value at de-serialization time.
Avro Enum default value is only supported in Avro-1.9+, so having such kind of alignment could help users, who are still using older Avro versions.

Research direction
Start by locating fast-avro's fast-class generation path and comparing its unknown-enum handling with vanilla Avro deserialization behavior. Done means class generation no longer fails on an unknown enum value, while deserialization preserves the vanilla Avro failure timing and works for users on older Avro versions.
