Function f32s_to_f64 

pub fn f32s_to_f64<const N: usize>(src: &[F32; N]) -> [f64; N]

Converts a wire array of little-endian f32 to [f64; N].

This is the Rust equivalent of libfranka’s RobotState::floatarray<N>::operator std::array<double, N>() (rbk_types.h): the robot streams float, the public API is double.
