Metage2Metabo v1.6.1

Fix

• Fix an issue with host keys ("host_prodtargets", "host_scope", "comhost_scope" and "host_unprodtargets") not appearing in comm_scopes.json file. But these keys used the old behavior of Metage2Metabo (possible unproducible seeds are contained in them). Host handling by Metage2Metabo will be modified in a future release.
