DEV - Remove feature collections from React and Redux

### Overview

We need to remove redundant storage of Service Requests on our app in order to improve our load time on the Map

### Action Items

- [x] Rip out all dispatches that update the Redux state's service requests
- [x] RequestsLayer no longer sets data
- [ ] Implement data fetchers
- [ ] Socrata API (use DataService.js)
- [ ] HuggingFace (via service worker)
- [ ] consider making another worker for streaming in new data, separate from UI
- [x] Implement controller for service requests
- [ ] implement lightweight data service to listen to redux for changes to filter parameters (e.g. RequestService)
- [ ] hook everything up
