Analyze code coverage of numba-jitted functions

[timmens]

What would you like to enhance and why? Is it related to an issue/problem?

Currently numba-jitted functions are ignored by codecov. To get a better understanding of the coverage of our code base we also want to learn about the coverage jitted functions.

Describe the solution you'd like

Disable numba-jitting on the runner / python-version that uploads the code coverage, but not on the others. The environment variable that has to be set is:

export NUMBA_DISABLE_JIT=1

Problems

Running the test-suite results in errors when JIT is disabled.
