Sometimes is usefull to give a contextual information to a field.
Other protocols like protobuf support annotations through what they call
Option <https://protobuf.dev/programming-guides/proto3/#customoptions>
which allows the following customization (uuid field annotation):
```
message FarmerRegisteredEvent {
string uuid = 1[(pi2schema.subject_identifier) = true];
oneof personalData {
ContactInfo contactInfo = 2;
pi2schema.EncryptedPersonalData encryptedPersonalData = 6;
}
google.protobuf.Timestamp registeredAt = 4;
string referrer = 5;
}
```
Would it be possible to add such metadata information in an avro schema?
