FIX - WMS should support CRS:84 CRS

[Bang Pham Huu]

According to OGC WMS 1.3.0 standard:

The <EX_GeographicBoundingBox> element (see 7.2.4.6.6) is conceptually similar to a BoundingBox in which
the attribute CRS="CRS:84" is implicit. However, <EX_GeographicBoundingBox> shall not be used as a
substitute for <BoundingBox CRS="CRS:84">. If the server wishes to provide bounding box information in the
CRS:84 CRS, then a separate BoundingBox element explicitly naming CRS:84 shall be included in the service
metadata

In WMS GetCapabilities response, for each Layer element, it should contain the <BoundingBox> element for CRS:84 CRS

• NOTE: OGC CITE WMS 1.3.0 conformance tests requires WMS GetMap requests with CRS:84 CRS e.g.

<BoundingBox CRS="CRS:84" minx="-180.0" miny="-90.0" maxx="180.0" maxy="90.0"/> // NEW element
<BoundingBox CRS="EPSG:4326" minx="-90.0" miny="-180.0" maxx="90.0" maxy="180.0"/> // Existing element

Also WMS GetMap request should support the request with bbox in CRS:84 (minLong,minLat,maxLong,maxLat), e.g.

http://localhost:8080/rasdaman/ows?
service=WMS&version=1.3.0&request=GetMap&bbox=145.178167420814475,-41.74864253393665336,155.9749999999999943,-32.29864253393665052&crs=CRS:84&width=1010&height=884&layers=test_raster:output&styles=&format=image/png&transparent=TRUE
