Two new options have been added to PlotEquiMap():
- lab_dist_x: increase/decrease the distance of the longitude labels to the box borders
- lab_dist_y: increase/decrease the distance of the latitude labels to the box borders. By default, these two options are disabled (NULL value) and the distances used are the optimal ones, depending on the size of the plot and of the labels; however, in some circumstances (particularly with map compositions), the distance might be too much close/far to the box. In these cases, users can modify the distance with these options. Values greater than one increase the distance.
