Capabilities: Handle more bbox elements

[fgravin]

It seems that the bounding boxes of the layers are only fetched from the BoundingBox element of the layer in the getCapabilities.
eg.

<BoundingBox CRS="EPSG:2056" minx="2.1e+06" miny="105000" maxx="2.85e+06" maxy="1.4e+06"/>

Additionally, it could exist more elements about the layer extent.

• EX_GeographicBoundingBox
• ows:WGS84BoundingBox

Those elements are in EPSG:4326 which simplifies the process afterwards, as it's a standard CRS.

eg.

<ows:WGS84BoundingBox>
  <ows:LowerCorner>5.140242 45.398181</ows:LowerCorner>
  <ows:UpperCorner>11.47757 48.230651</ows:UpperCorner>
</ows:WGS84BoundingBox>

<EX_GeographicBoundingBox>
  <westBoundLongitude>0.659866</westBoundLongitude>
  <eastBoundLongitude>10.8359</eastBoundLongitude>
  <southBoundLatitude>36.982</southBoundLatitude>
  <northBoundLatitude>48.7511</northBoundLatitude>
</EX_GeographicBoundingBox>

is that for WMS or WFS? Edit: looks like it's for WMS. The WMS spec does not allow WGS84BoundingBox elements so I'm a bit surprised, does that really happen? do you have an example?

As for EX_GeographicBoundingBox, indeed it's missing. I'll add support for it.

The exemple above come from WMS and WMTS.
