@dlr-eoc/services-ogc:
- Used to depend on @boundlessgeo/jsonix, because this fork of @highsource/jsonix worked with angular8. However, that fork declared a couple of variables globally, which now no longer works with angular9 and the ES2015 target.
- Created an own fork under @michaellangbein/jsonix that adresses both the global variables issue and allows building to es2015.
- All imports of 'jsonix' have been updated to '@michaellangbein/jsonix'
- As a consequence of using this package, the sourceIsEvt hack in src/index.html is no longer required and has been removed.
