McLachlan_BSSN.m: Change from old TensorTools to new Kranc Jacobians for MP
The Jacobian gridfunction groups are no longer hard-coded into McLachlan, and the Coordinates thorn is no longer inherited. Instead, the user must use GenericFD parameters to specify the Jacobian to use. The new Kranc Jacobian implementation allows a single map to be specified on which the Jacobian is not applied, which greatly improves performance in typical multipatch simulations. To use the new Jacobian method with Llama, set
GenericFD::jacobian_group = "Coordinates::jacobian"
GenericFD::jacobian_derivative_group = "Coordinates::jacobian2"
GenericFD::jacobian_identity_map = 0
