Scenario 2 errors out with a different center-frequency/grid-size due to mismatch in material mask / grid size

Describe the bug

Changing the center_frequency to something outside of 5e5 changes the grid size, but the material mask for Scenario 2 is loaded from the data file and not resized to the grid size, so the code errors out.

One option would be to re-interpolate the material masks to the new grid.

Steps to reproduce

Edit plot_scenarios.py to use a different center_frequency (e.g. 1e6), and then run it.

Include a description of your setup including:

Python version: 3.10.12
OS version and name: {'system': 'Linux', 'node': 'ip-172-31-27-213', 'release': '5.15.0-1031-aws', 'version': '#35~20.04.1-Ubuntu SMP Sat Feb 11 16:19:06 UTC 2023', 'machine': 'x86_64', 'processor': 'x86_64'}

Expected results

Steady-state simulation completes successfully.

Actual results

Edit plot_scenarios.py to use a different center_frequency (e.g. 1e6), and then run:
