rasql_clip with Multipolygon

[Bang Pham Huu]

Current, rasdaman with clip operator only supports 2 types of WKT: POLYGON ((30 10, 40 40, 20 40, 10 20, 30 10)) and LINESTRING (30 10, 10 30, 40 40).

The vector data from GIS shapefile is usually in Multipolygon type (e.g: a territory containing land and islands). Then, rasdaman needs to support this to be useful in real use cases.

Example of a Multipolygon (2 polygons) from ​https://en.wikipedia.org/wiki/Well-known_text is:

MULTIPOLYGON (
  ((40 40, 20 45, 45 30, 40 40)), -- Polygon1: only exterior 
  ((20 35, 10 30, 10 10, 30 5, 45 20, 20 35), (30 20, 20 15, 20 25, 30 20)) -- Polygon2: 1 exterior and 1 interior
)

Is this one fully addressed though?
