Is your feature request related to a problem? Please describe.
Currently, the configuration parsing is done by a single submodule [ref], which is creates issues with maintenance as more functionality is introduced.
Describe the solution you'd like
Using a configuration validation mechanism that is more standardized would make the developer and user experience much better. Some examples are (and this is by no means an exhaustive list):
| Package | Documentation | Example |
|---|---|---|
| Cerberus | https://docs.python-cerberus.org/ | https://stackoverflow.com/a/46626418 |
| PyDantic | https://docs.pydantic.dev/latest/ | https://stackoverflow.com/a/61021183 |
| Marshmallow | https://marshmallow.readthedocs.io/en/stable/ | https://stackoverflow.com/a/63739747 |
Describe alternatives you've considered
N.A.
Additional context
It would make sense to eventually move GaNDLF's various functionalities to something like Hydra, and this could potentially be a good starting point.
