Python: Add API for importing well log data

Implement comprehensive Python API for importing well log data into ResInsight
well paths using lists of float values.

Core implementation:
- RigImportedWellLogData: Data storage class inheriting from RigWellLogData
- RimImportedWellLog: Scriptable model class for Python GRPC interface
- RimcWellPath_addWellLogInternal: GRPC method using key-value store for data transfer
- well_path.add_well_log(): Python API with validation and error handling

Features:
- Simple API: well_path.add_well_log(name='LogName', values=[1.0, 2.0, 3.0])
- Comprehensive input validation and type checking
- Efficient data transfer via key-value store mechanism
- Proper error handling with cleanup on failure
- Integration with existing well path functionality

Testing:
- 10 comprehensive unit tests covering all functionality
- Validation of input types, error conditions, and edge cases
- Integration testing with well path creation

Usage example included in PythonExamples directory demonstrating
import of gamma ray, porosity, and permeability log data.
