Parse direction label after point clause and sort Python imports
In a ds9 region file a name can be given to a polygon
in the comment after the polygon
definition.
This name can currently be read by the ds9 region file reader schaapcommon.
However, it is also allowed (at least ds9 accepts it) to specify the name in the comment after the optional point
definition, after the polygon
definition.
This MR extends the reader, to also parse the comment after a point
, and check for a name for the facet there.
