Problem:

From within Oracle it is common to store GUIDs in a `RAW(16)`. When Debezium streams CDC events to Kafka it streams a Base64 encoding of the byte[]. This means all consumers need to have logic that decodes from Base64, then convert the `byte[]` into a GUID.

Suggestion:

There should be a `Raw16GuidToString` transform package into Debezium that converts the Base64 encoded value into a GUID string all programming languages understand natively. For example: Within the Source connector`KwnMrgaqRaqi8d0OTARySQ==` is transformed to `2b09ccae-06aa-45aa-a2f1-dd0e4c047249` before it is written to the Kafka topic.

Justification:

This would cut down on the need for each consumer needing to have the Base64 > byte[] > GUID logic. Instead, the transformation would happen once (within the Source Connector) and downstream, consumers would receive the GUID string.
