Implement internal GridOverrider strategy pattern (#821)

* Add composable index strategies for SEG-Y header transformation

This commit introduces a new module for index strategies that replaces the monolithic GridOverrider with a set of single-responsibility IndexStrategy classes. The new structure allows for better composition and selection of strategies via the IndexStrategyRegistry, while maintaining compatibility with the existing ingestion behavior. Additionally, unit tests for the new strategies have been added to ensure functionality and correctness.
