0.6.2 2025-10-20

Add optional use of fused multiply-add, enabled for python distributions.
This substantially improves floating-point roundoff; cubic method now shows
O(1e-14) peak roundoff error even under extrapolation of a quadratic function,
and 0-4 epsilon roundoff inside interpolating region.
Overall effect on throughput performance is neutral.

Added

• Rust
  • Add fma feature

Changed

• Rust
  • Use Horner's method for evaluating normalized cubic hermite spline
  • If fma feature is enabled, use FMA in cubic and linear methods where possible
• Python
  • Enable fma feature for python distribution
  • Update pgo profile data and benchmark plots
