Make sure statistics curves are recomputed on flag change
When toggling "Discard Missing or Incomplete Realizations", make sure the statistics is recomputed and the ensemble plots updated.
* 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
* Make sure all curve values are set correctly for plot orientation
* Make sure depth zoom is propagated to the Qwt plot
* Expand min/max value range to allow more space around curves
* Use int values to represent RFT segment branch number
Add reader for RFT data using opm-common
Extend RFT curve with support for RFT segment data
