Bad python_requires in setup.py prevent build

[Lyamc]

setup.py needs to be updated so that

    python_requires=">=3.*",

is changed to

    python_requires="==3.*",

Fixes this error:

  × Getting requirements to build wheel did not run successfully.

      error in justlog setup command: 'python_requires' must be a string containing valid version specifiers; Invalid specifier: '>=3.*'
