[Feature Request] Improve UniForm Hudi support for Lists/Maps and Schema Evolution

[the-other-tim-brown]

Feature request

Which Delta project/connector is this regarding?

• Spark
• Standalone
• Flink
• Kernel
• Other (Unfiorm)

Overview

The UniForm support for Hudi does not properly translate Map & List fields and the testing does not validate that the schema can be evolved in the source Delta Lake table and properly reflected in the Hudi table.

Motivation

UniForm users will benefit from a more complete translation between Delta Lake and Hudi.

Further details

The XTable project has already handled such translations and the approach can be ported over to this repo.
