initial implementation
Provides an initial implementation of the library.
Publication to test PyPI via CI at https://gitlab.developers.cam.ac.uk/uis/devops/lib/fastapi-openapierrors/-/jobs/354889 and it can be seen on PyPI at https://test.pypi.org/project/fastapi-openapierrors/0.9.0/.
I've added the limited-scope TEST_PYPI_API_TOKEN
CI variable but waiting until merge to deploy fully to live PyPI.
