Adapt petascope to use new project() function

[Dimitar Misev]

Petascope WMS should be adapted to use the new project() function (2):
​http://doc.rasdaman.org/04_ql-guide.html#the-project-function

What this means in particular:

• Extend, scale, and subset on top of project should be removed from the rasql query
• The scale extents should be specified as widthOut and heightOut parameters to project()
• The WMS bbox should be specified as boundsOut parameter
• The rest stays the same as before

[Dimitar Misev]

The WMS bbox should be specified as boundsOut parameter

Just be careful, as I learned after a bunch of unnecessary debugging, the coordinate order in the WMS bbox is different from the one in the project function (which is "xmin, ymin, xmax, ymax").
