Fixed SDK-426 scrubbing for namedtuples

[danielmorell]

Description of the change

This change fixes an issue where named tuple fields included in scrub_fields were not being scrubbed/redacted before the namedtuple was serialized.

This was caused by the _serialize_frame_data() method running ScrubRedactTransform() without checking the scrub_fields values before serializng the namedtuple. As a result by the time we came to scrub the namedtuple with the scrub_fields values had been serialized to a string.

This PR creates an instance of ScrubRedactTransform during init() that is passed the scrub_fields and used during both _serialize_frame_data() and _transform().

While makeing that change I noticed that ScrubRedactTransform can further do the work of ScrubTransform if it is passed the same arguments during initialization. Because of that I removed ScrubTransform from the list of transforms since ScrubRedactTransform will do both now. This futher reduces the total number of traversals and transforms we need to do of the data, making it more efficient.
