Make 1.3.0 default WMS version

[PedroVenancio]

This issue #248 and PR #307 had pretended to change the default WMS version to 1.3.0, but I believe it still needs some improvement, because version 1.1.1 is still hardcoded in some places:

https://github.com/search?q=repo%3Ageopython%2FGeoHealthCheck%201.1.1&type=code

Also, changing from 1.1.1 to 1.3.0 implies some differences, for instance:

• From SRS to CRS;
• BBOX from xmin,ymin,xmax,ymax to ymin,xmin,ymax,xmax

I've tried to change locally all default 1.1.1 to 1.3.0, but WMS Drilldown keeps using version=1.1.1, and I could not find why.

At this time I think 1.3.0 should be the default for all tests of GHC, and it seems it is not, even after #307.

Context (please complete the following information):

• GeoHealthCheck Version 0.9.0
