remove hardcoded geometry assumptions from geometry resource

[krwood]

We should have a common geometry resource module (living somewhere like ndlar_flow/src/common/resource/geometry.py) that is completely void of any hardcoded assumptions about the geometry, and takes everything in from the appropriate yaml. For example, there are hardcoded assumptions about number of tiles per module and number of modules per detector here: https://github.com/DUNE/ndlar_flow/blob/develop/src/proto_nd_flow/resources/geometry.py#L730C69-L734
