Update Git Module CatAtom2OSM

[justb4]

CatAtom2OSM is included in this repo as a GitHub Module:
catatom2osm @ 5ac20ad

There have been updates to CatAtom2OSM like PR OSM-es/CatAtom2Osm#121 . To use the latest version within CatAtomApi the Module should be updated/pushed. I think something like:

cd CatAtom2OSM
git checkout master && git pull
cd ..
git add CatAtom2OSM
git commit -m "updating submodule CatAtom2OSM to latest”
git push
