change pybmds version location to root instead of pyproject.toml

[shapiromatron]

move the version string from the pyproject.toml to the project package root. There were bugs when trying to get the version when using an editable install of the package.

Fix unrelated bug where std::max was throwing an error in the windows build - see error log here: https://github.com/USEPA/BMDS/actions/runs/10202894684/job/28228004905#step:7:711
