Make tuple treated the same as list and set

[Outfenneced]

Summary

Treats tuple the same as list and set in the flatten conversion. Also adds in two tests to prevent regression. Also collapses the or chain on the isinstance call for increased readability and ease of additions/subtractions.

Bug Fixes/New Features

• Adds tuple to the structures flatten can support

How to Verify

Added two tests to verify:

• A tuple with 1 or more values is expanded to its enumerated form: test_tuple
• An empty tuple is left as an empty tuple and not expanded further test_empty_tuple

Side Effects

None

Resolves

None

Tests

All tests pass along with the two added tests: test_tuple and test_empty_tuple
