Fix/text locator heatmap

Author: warm-coolguy

packages/clients/textLocator/CHANGELOG.md

@@ -4,6 +4,7 @@
 
 - Breaking: Adapt client to new backend API. Previous versions are no longer runnable due the backend API change.
 - Feature: Implement document search, that is, the AddressSearch bar now also offers results for documents and clicking on one will retrieve a list of toponyms from the backend and resolve them against the gazetteer. Previously, we had a "get all documents regarding place" functionality. Now, a "get all places regarding document" feature is implemented. Additionally to the AddressSearch, this can be triggered on documents found in the previously implemented way; the "get all places regarding document" functionality is available from within the GeoSearch result display.
+- Fix: Adjust heatmap feature to match the new data structure and have it working again.
