Function bridge_dimensions 

pub fn bridge_dimensions(low: &[f64], out: &mut [f64]) -> bool

Topological dimension-bridging: lift a lower-dimensional sample low (e.g. a 1-D audio sample, or a 7-axis WaveCoord) into a higher out-dimensional manifold coordinate, zero- padding the new axes. Returns false if out is too small. The 1D→10D bridge.
