range subsetting on single band
|Reported by:||dmisev||Owned by:||mdumitru|
When the coverage has a single band range subsetting fails right now. It fails because for single band the type in rasdaman is typically not a struct. To fix it the range constructor in WCPS probably needs to be adapted, if there's only a single band it should simply ignore it when translating to rasql.
E.g. if there's a band band0 in petascope, then c.band0 in WCPS would translate to simply c in rasql, not c.band0
