Changes to support sharrow on 2-zone model

[jpn--]

trafficstars

This PR has a number of changes made in support of sharrow on the new "canonical" 2-zone example, although as it turns out none of these changes really alter how ActivitySim runs...

• Update the minimum version for numba to 0.57 (to access np.nan_to_num as a numba function).
• Improve runtime logging of sharrow and non-sharrow code to disambiguate interaction-simulate steps from simulate steps.
• Improve debugging script that is activated in interaction-simulate steps only in sharrow test mode, when sharrow and non-sharrow utility functions differ.
• Documentation updates
• Change to test configs for joint_tour_frequency_composition.
