Petascope parses result from RAS_MARRAY_TYPES properly

[Bang Pham Huu]

Currently, in Petascope it parses by "AS", if a collection contains "AS" in its name e,g: S2_L2A_SOUTH_TYROL_RAS_new7_Cell, petascope just returns empty string instead.

    private String parseMarrayStructure(String marrayLine) throws RasdamanException {
        String[] parts = marrayLine.split("AS");
        if (parts.length < 2) { //invalid line
            return "";
        }
        String marrayStructure = parts[1].trim();
        String[] marrayStructureParts = marrayStructure.split("MDARRAY");
        if (marrayStructureParts.length < 2) { //invalid line
            return "";
        }
