Eliminate test dependency: numpy

[asnare]

Changes

What does this PR do?

This PR eliminates numpy as a (direct) project dependency: we're only using it in one specific location in a test, and it can be trivially replaced with code from the standard library.

It's worth removing: compatibility with other dependencies restricts us to a really old version, and for some of the supported platforms (and python versions) there's no prebuilt package available. This leads to unnecessarily long test/CI because numpy needs to be compiled from source during (virtual) environment setup.

Caveats/things to watch out for when reviewing:

The integration test that runs the updated pipeline is: test_profile_execution_config_override
