Generalized Wendland covariance function for a given distance matrix.

Computing the Matern covariance function for a matrix of distances.

gw_cov(dists, sigsq, phi, kappa, mu)

`dists`	a numeric matrix representing the distance between spatial entities.
`sigsq`	the `\sigma^2` parameter from the Matern covariance function.
`phi`	`\phi` is the range of the covariance function.
`kappa`	`\kappa \in \{0, \ldots, 3 \}`.
`mu`	`\mu` controls the smoothness of the covariance function
