Implements interval-based diameter and roughness configuration for MSW completions
while maintaining backward compatibility with existing single-value approach.
- Add RimDiameterRoughnessInterval class for individual MD intervals
- Add RimDiameterRoughnessIntervalCollection for managing interval collections
- Extend RimMswCompletionParameters with interval-specific mode support
- Support both metric and field unit systems
- Provide validation and overlap detection for intervals
