ortools requiring protobuf>=4.21.5. about maxfield

[flutesa]

I encountered the same issue while using

1. MacOS Ventura 13.1
2. Python 3.9

It was able to fix it after doing these steps:

1. Replace in setup.py on line 10 version
   protobuf==3.19.4
   to
   protobuf==4.21.12

2. Then while running the script by command
   maxfield-plan /Users/aguseva/PycharmProjects/ingress/maxfield/my_portals.txt --num_agents 2 --num_cpus 0 --output_csv
   I was having this problem:
   AttributeError: module '__main__' has no attribute '__spec__'
   To fix it I changed my command to
   python3 -m maxfield-plan /Users/aguseva/PycharmProjects/ingress/maxfield/my_portals.txt --num_agents 2 --num_cpus 2 --verbose --output_csv
   And in setup.py on line 12
   scripts=['bin/maxfield-plan'],
   to
   scripts=['bin/maxfield-plan.py'],
   And in your file system add '.py' to this file name accordingly.
   Finally, it was fixed and worked out for me!

🎉 Wish you success and hope it'll be working fine for you too! Have joyful game)
