/**
 * Finds the parameter 't' of the nearest point on a 1D Hermite spline
 * function graph to a reference point. The curve is defined by (t, p(t)).
 * This version is optimized to avoid allocations.
 *
 * @param {number} ref_t - The 't' coordinate of the reference point.
 * @param {number} ref_p - The 'p' coordinate of the reference point.
 * @param {number} p0 - The start value of the spline (at t=0).
 * @param {number} p1 - The end value of the spline (at t=1).
 * @param {number} m0 - The tangent at the start.
 * @param {number} m1 - The tangent at the end.
 * @returns {number} The parameter 't' of the nearest point. This value is always in [0..1] range
