43c8f2e6a5 Add initial project configuration and build scripts for omath library
- Created pixi.toml for project metadata and dependencies management.
- Added formatting script (fmt.cmake) to ensure consistent CMake file formatting.
- Implemented benchmark execution script (run.benchmark.cmake) to run benchmark tests.
- Developed example execution script (run.examples.cmake) to run example applications.
- Created unit test execution script (run.unit.tests.cmake) to run unit tests.
