Sets the dispersal matrices for the Lattice dispersal model.

Each matrix has 'patch number' x 'patch number' cells unless the lattice model is the absorbing boundaries model where we add the sink patch.

The "dispersal_lattice_range" parameter defines the number of neighbouring patches to disperse into. Option 1 sets this number to 4 (left and right, up and down patches) whereas option 2 allows to disperse to the 8 neighbouring patches, including the patches on the diagonals.

The reduced dispersal matrix contains the indices of the patches to which each patch is connected.

The connected patches are further ordered in descending order of the migration rates. The migration rates are stored in a reduced dispersal matrix. The original dispersal matrices are cleared (de-allocated). This offers a double speed-up compared to the classical method.
