Describe the bug (actual behavior)

Data masking works fine for JSON fields but masks if the key or value fields are defined as basic data types like string. Not sure if this is expected behavior by reading the documentation. My expectation is only mask the named fields in json/avro etc.

Your installation details

Here are the properties I am using

kafka.clusters[0].masking[0].type=MASK
kafka.clusters0.masking0.fields=NAME
kafka.clusters0.masking0.topicKeysPattern=.*
kafka.clusters0.masking0.topicValuesPattern=.*

Steps to reproduce

create two different topics,
One with json keys and put some json data with NAME field in them.
Another with key/value as string. Write some randome data to it.

Only the first topic data with JSON data NAME field should be masked
The second topic key/value shouldn't be masked

It's an expected behavior, even if the message is not json/avro we still try to mask it given deserializer we have, and applying a string one is quite easy here. This makes more sense than not doing that if we can, IMO.
Let me know if there are any other questions.
