Bare metal cubic spline interpolation with Rust [no\_std]
Given 2d points on the plane, calculate piecewise polynomials which connect
the points in a most smooth way.
There can be an arbitrary (const) number of points. Due to limitations in
num-trait or my coding abilities, only f32 coordinates are supported.
