Enhancement: Add Configuration Validation

[berntpopp]

Implement validation for configuration files and command-line arguments to ensure that all required parameters are provided and are in the correct format. This will help prevent runtime errors caused by invalid configurations.

Acceptance Criteria:

• Implement validation checks for all configuration parameters.
• Provide clear error messages when invalid configurations are detected.
• Ensure that the tool exits gracefully when invalid configurations are provided.
• Update the documentation to describe the validation rules and how to fix common configuration errors.
