Repeated key literals in insMap dictionary in testgen.py

[jordancarlin]

I was looking into enabling ruff on this repo like we did for the main cvw repo discovered the following error.

The insMap dictionary in testgen.py has several duplicate entries. These duplicate entries have different mappings, so it's not as simple as just deleting the duplicates. Error message is included below. Looks like @HamzaYusufJamal is the last one that touched this. Can you look into it?
