Read configuration from pyproject.toml

These days most Python tools support getting their configuration from pyproject.toml. This is nice to avoid clutter from many files in the root of a repository. It would be nice if bobtemplates.plone supported this as an alternative to bobtemplate.cfg

should be doable, just keep in mind that this file is currently used to find the root of the package.
