Edge case test of aerodynamic convert

[Gorkowski]

suggestion (testing): Add test cases for extreme values in aerodynamic_to_physical_radius conversion

Consider adding test cases for extreme values (very small and very large) to ensure the conversion function handles these cases correctly. This would improve the robustness of the test.

physical_radii = convert_aerodynamic_to_physical_radius(
    aerodynamic_radii, pressure, temperature, particle_density,
    aerodynamic_shape_factor, reference_density
)
