Tests for InfectionsWithFeedback class

[dylanhmorris]

All existing tests were able to pass with a bug in the InfectionsWithFeedback class. Only attempting to render the extending_pyrenew.qmd tutorial revealed it. We should have:

1. A test confirming that InfectionsWithFeedback can be instantiated and sampled.
2. A test comparing infections with feedback computed using the class to a manual computation.

@dylanhmorris How should the additional tests be different from the ones here?
As far as I understand this test verifies that InfectionWithFeedback class can be instantiated, sampled from, and compares the
Rt and Infections sampled from this class with the ones computed using a more straightforward method.

This is a lesson to me always to write a reprex, since the tests you're pointing to are almost exactly what I described and evidently didn't catch the bug. Let me investigate.

@dylanhmorris Were you able to investigate?
