RimEclipseCase_exportMswCompletions takes WellPath objects and an
explicit export folder. RicfExportMsw resolves the well path name and
export folder and forwards to it. Case.export_msw() in Python is kept
and emits a DeprecationWarning.
Based on branch https://github.com/OPM/ResInsight/tree/system-msw-refactor
- Move completion settings to property of well path
- Rename to RimFishbones
- Export implicit COMPSEGS for fishbones main bore
- Add valve for each branch
- Increase version number to be able to handle import of legacy project files
