Coordinate Info Plugin geomag calculation

[jolevesq]

The geomagnetic calculation is now https

https://geomag.nrcan.gc.ca/service/tools/magnetic/calculator/?&callback=jQuery33109880967166820425_1533915134123&latitude=52.50606969511178&longitude=-99.27152207689319&date=2018-08-10&format=json

We can now remove the if to check if the viewer is http inside the index.ts file.

// Magnetic declination service is only available in http
        if (window.location.protocol === 'http:') {

@mweech Do you want us to create plugins issue inside plugins repo?

Great.

I'd vote to keep all issues in the one spot (so we don't need to be checking multiple lists). Though I can be overruled :'D

[mweech]

Overruled!
