Description: Constructs multi-resolution thin-plate spline (MRTS) basis
        functions on the sphere and fits the corresponding
        multi-resolution mixed model (MRMM) by generalised least
        squares with a tapered Matérn residual covariance, including
        kriging-style prediction with closed-form standard errors.
        Implements the system described in Huang, Huang, and Ing (2025)
        "Multi-Resolution Spatial Methods on the Sphere: Efficient
        Prediction for Global Data", Environmetrics,
        <doi:10.1002/env.70092>. Heavy basis computations are written
        in 'C++' via 'Rcpp' with optional 'OpenMP' parallelism.
