Add capability for specifying additional options with the gdal:contour processing algorithm

Description

Would it be possible to add the OPTIONS parameter to the list available with gdal:contour in QGIS 3?
For example, it would be good to be able to specify the additional option '-fl <contour1> <contour2> etc' to allow generation of contours at user-defined levels.
It looks like this requires quite modest modification to processing\algs\gdal\contour.py. Including OPTIONS in the class attributes and adding 'self.addParameter(...' to initAlgorithm and 'arguments.append(options)' to getConsoleCommands seems to work.

Thanks,

Geoff Kimbell
