Calibrating The Meuse and Rhine Wflow Hourly Models

This renewed effort in calibrating the two largest operational hydrologic models for the Netherlands is intended to address:

1. Primarily timing lead and lag times in event onset and arrival on a per catchment basis.
2. Improving high and low flow simulation accuracy.
3. Providing uncertainty estimates that stem from calibration.
4. Reproducibility.

A workflow is built for the Meuse, which is then deployed for the Rhine.

This workflow is borrowing and expanding on the work done for:

1. Interreg (calibration, Laurene Bouaziz and Anais Cousanon)
2. Puget (Joost Buitink and Brendan Dalmijn)

TODO: names and characters, licensing, projects any additional names

The innovations and contributions of this new effort in model calibration are:

1. Event timing metrics as calibration objectives (mean timing offset and std of lead/lag)
2. Cascading calibration (dependency tree solver)
