Returns the score with respect to untransformed parameters.
Calculates the score vector for the profiled log-likelihood of the mixed effects model with respect to the parameterization in which the random effects covariance matrix is represented in its full form (not using the Cholesky factor).
score_re is taken with respect to the parameterization in which
cov_re is represented through its lower triangle (without taking the Cholesky square root).
