EV and Network Opportunity Maps

[steve9164]

Do the NOM & EV maps modifications properly (previously done incorrectly in https://github.com/TerriaJS/saas-catalogs-public/pull/29). There's also more modification here.

~Doing a diff to https://github.com/TerriaJS/saas-catalogs-public/blob/main/nationalmap/dev.json I get:~

                             "Root Group/Renewable Energy/Bioenergy/Western Australia/Broiler Litter Production"
                           ]
                         },
-                        {
-                          "type": "ckan-item",
-                          "name": "Cereal straw",
-                          "id": "306dd5a9",
-                          "url": "https://catalogue.data.wa.gov.au",
...
-                        },
                         {
                           "type": "ckan-item",
                           "name": "Dairy Effluent",

~which looks like it's reverting half of https://github.com/TerriaJS/saas-catalogs-public/pull/30. Any idea why?~

Edit: I now see that https://github.com/TerriaJS/saas-catalogs-public/pull/36 removes the same dataset from test. So it's probably intended!
