Do stuff with Mappings and more

🚀 Why use MappingTools?

Built for developers who need more than just standard dictionaries.

Problem	Solution
Deep JSON Diffing	Use flattened() to collapse nested JSON into single-layer paths for easy comparison.
Data Collisions	Use inverse() to swap keys/values without losing data (automatically creates sets for duplicates).
Slow Config Loading	Use MeteredDict to profile exactly how many times your app reads specific config keys.
Quick Serialization	Use simplify() to instantly convert Dataclasses, DateTime, and custom objects into pure Dicts.
