Updates build and fniycbo options

- fniycbo options via isfniycbozero
  - Makes fniycbo-switch index-dependent
  - Fixes switch for double-null geometries
- Hardens checkver to allow code execution without connection to PyPi
- Implemements build and install using pyproject.toml
- Updates Workflows to ensure compatibility of Forhton with numpy>2.0
