[RFC] Mac vs. Others precision

[oerc0122]

Description of the error During the development of #687, it was found that the test precision had to be reduced (to ~1e-6 vs. ~1e-10) on several tests (Analysis/test_scattering:test_{ccf,dcsf,ntdsf}) due to inconsistencies in values between Mac and Ubuntu/Windows.

This is probably due to the Arm-compiled Numpy libraries being optimised differently, and does not necessarily imply problems with these libraries.

Describe the expected result Same results on all systems.

Describe the actual result Slightly different results (~1e-7)

Suggested fix N/A. Noted here for future investigation if needed.

Additional details N/A
