Description
Describe the enhancement requested
Problem:
When ingesting into databases that don’t support Arrow’s dictionary type, Go users must manually call compute.Cast on each dictionary array to strip the encoding. There’s no single “flatten” helper.
Solution:
Add a Flatten function that accepts a dictionary array and returns a non-dictionary version in one call.
