Added precomputed constants and lookup tables for sine/cosine functions generated with Sollya. These tables include: - Pi constants with different precision levels for float and double types - Sine approximation tables for fast trigonometric calculations - Angle reduction constants - KPi/16 inline constants for range reduction The data was generated using the 'spin sollya' tool and separated into multiple header files to reduce code size and improve organization. Files added: - npsr/trig/data/approx.h: Sine approximation tables - npsr/trig/data/constants.h: Pi and other trigonometric constants - npsr/trig/data/data.h: Main data header - npsr/trig/data/kpi16-inl.h: KPi/16 inline constants - npsr/trig/data/reduction.h: Angle reduction constants

Thanks @seiko2plus, this should probably have gone in with the first PR so it worked so I'm happy to get this in and then look at the more interesting generator 😸 |

Thank you @Mousius, now I can re-base numpy/numpy#29699 and make it ready for review. The generator is lives now in #5 |
