Fix tests on macOS

[ttytm]

Best #182 first, then C types can be updated here as well before a merge.

Apparently math works different on mac, needed to add a little tolarance for some tests.

Summary by CodeRabbit

• Refactor: Simplified the CI/CD pipeline by removing specific test configurations, enhancing the efficiency of the testing process.
• Test: Introduced platform-specific tolerance checks in various test functions, ensuring consistent behavior across different operating systems when comparing floating-point values.
• New Feature: Incorporated LAPACK and CBLAS functionality into the codebase for macOS, enhancing the software's capabilities on this platform.
• Refactor: Simplified code in several areas by using more concise syntax, improving code readability without altering functionality.
• Test: Enhanced test failure messages to include actual and expected values along with the tolerance, providing more detailed feedback during testing.
• Chore: Removed unused functions and updated function signatures to align with library usage, streamlining the codebase.

Walkthrough

The changes primarily focus on platform-specific adjustments for macOS, particularly in floating-point comparisons and LAPACK library usage. The CI/CD pipeline is simplified, and test execution steps are streamlined. The codebase now incorporates LAPACK functionality for macOS, and the test assertions have been updated to use tolerance checks for floating-point comparisons.

Changes
