Adds `std::formatter` specializations for `Mat`, `Vector2`, `Vector3`, and `Vector4` types, enabling the use of `std::format` for these types.
This simplifies formatting and printing of these mathematical objects, improving code readability and consistency.
Also adds a hash function specialization for Vector3.
Updates unit tests to include more accurate assertions for camera projections.
Adds .idea/workspace.xml to .gitignore to prevent tracking local IDE settings.
Refactors some test fixture class names for consistency.
Adds project-specific IDE settings to improve code style consistency and development environment.
Removes the .idea directory from the .gitignore file, as these files are now intended to be part of the project for consistent IDE configuration across contributors.
Adds less than, greater than, less than or equal, and greater than or equal operators to the Vector2, Vector3 and Vector4 classes.
The comparison is based on the lengths of the vectors.
Adds corresponding unit tests.
The changes encapsulate the matrix tests within an `#ifdef` block, allowing conditional compilation based on whether `OMATH_ENABLE_LEGACY` is defined. This enables the legacy code to be compiled only when needed.
