Geocaching Height : no more working (June 2019) since link has changed #42

I've got the error :
TypeError: Cannot read property 'length' of null at getCoords (userscript.html?id=e50fbb23-e0b0-4d26-a4f1-aedc68293fb5:60)

(seems to be on line 54 : return (target && target.href && (matched = target.href.match(pattern), matched.length === 3))

Currently lat and lng are grabbed from the link with id ctl00_ContentBody_uxViewLargerMap
but this kind of link seems to have changed, since a recent update on maps.

I actually have this link :
<a_ id="ctl00_ContentBody_uxViewLargerMap" title="Voir une plus grande carte" href="/play/map/GC1Y014" target="_blank" rel="noopener noreferrer">Afficher la carte agrandie</a>

Locally I've replaced the line :
const coords = getCoords("ctl00_ContentBody_uxViewLargerMap");
with :
const coords = {lat: lat, lng: lng};

as the page seems to expose directly vars called lat and lng as I can se on the source of the page :

<script type="text/javascript">   var isLoggedIn = true;   var lat=45.879233, lng=6.887133, guid='0157909c-6d0d-4ef7-9f07-4dd858dc1f89'; </script>

Changed getCoords() method
Cache listing on no longer has coordinates available in an element with a known id (issue #42).  Now gets lat and lng global variables from content context using unsafeWindow.  Alternative strategies would be to parse from document.body.innerHTML, or search all A.href strings for likely looking coords.

I think this is fixed in the Height Development branch. If it works for you too @Krevo, I'll deploy the fix tomorrow.
