StateMapGenerator failure due to Pillow removing `font.getsize`

[malonkey1]

When running the StateMapGenerator with current version of Pillow, the script fails:

Traceback (most recent call last):
  File "D:\steam\steamapps\workshop\content\394360\1521695605\map\hoi4statemapgenerator.py", line 640, in <module>
    main()
  File "D:\steam\steamapps\workshop\content\394360\1521695605\map\hoi4statemapgenerator.py", line 615, in main
    create_states_map_with_id(colors_replacement_dict, province_map, [round(255 * x) for x in water_color], args.font)
  File "D:\steam\steamapps\workshop\content\394360\1521695605\map\hoi4statemapgenerator.py", line 292, in create_states_map_with_id
    state_pixels[key] = (value, font.getsize(str(key)))
AttributeError: 'FreeTypeFont' object has no attribute 'getsize'

When rolling back to Pillow 9.5, the issue is resolved. This is likely due to font.getsize being removed from Pillow in version 10.0.0.
