* Compute average MD for intersections with a cell
* Create extractor for simulation well
* Remove rftReader from RifDataSourceForRftPlt
* Add function compute measured depth for RFT cells based on well path geometry
* Move statistics reader to well ensemble curve set
* Make sure both TVD and MD are cached if possible
* Add selection of grid case to use for estimation of measured depth (MD)
Add "Grid Model For MD" where the user can select a grid model. This grid model is propagated to a hidden field in EnsembleCurveSet. The grid model is then applied to RifReaderEnsembleStatisticsRft owned by EnsembleCurveSet
* Refactor interface to PdmObjectHandle and PdmFieldHandle
Return objects instead of passing in structures as parameters
* Add nodiscard to several functions
* Remove redundant this->
* Rename to ptrReferencedObjectsByType
Move AppEnum init to RifDataSourceForRftPlt
Simplify constructors for RifDataSourceForRftPlt
Rename enum names in RifDataSourceForRftPlt::SourceType
Add missing pressureDepthData in RimDataSourceForRftPlt
