Pull Request Overview

This PR introduces iterable map getters functionality to the Hive database library, providing convenient methods to retrieve and cast stored values to specific collection types (List, Set, Map) without requiring manual casting after retrieval.

• Adds new getter methods (getList, getSet, getMap, getListAt, getSetAt, getMapAt) to Box, LazyBox, and IsolatedBox interfaces
• Implements these methods across all box implementations with proper type casting
• Updates error messages to guide users toward the new casting methods
• Adds comprehensive test coverage for all new getter methods
