"""Label the parallel intersecting a given meridian
The method is called by `grid()` but can be used to overwrite the defaults.
Args:
m: meridian in deg
loc: location of the label with respect to `m`, from `['left', 'right']`
parallel: list of parallels to label, if None labels all of them
pad: padding of annotation, in units of fontsize
direction: tangent of the label, from `['parallel', 'meridian']`
