Upgrading osdatahub to work with Python 3.12, 3.13

[jmbraybrook]

Main purpose of this pull request is to resolve major incompatibility issues with python versions

This pull request has three main focuses:

• aim to support more recent versions of python 3.12 and 3.13.
• upgrade packages to the latest versions to ensure security.
• depreciating support for Python 3.7 as a result for compliance with security updates. (Python 3.7 is now depreciated as of June 27th 2023 with no further security updates.)

Issues Resolved

• Resolves a backwards compatibility problem with the TypeGuard dependency which has moved its functionality to a decorator model. - Update typeguard #89
• Typing for Geojson objects is now explicitly dict rather than Feature Collection. (Will need Reviewing)
