Merging additions in `ecoscope` fork

Things I've added in our fork that may be worth adding/reviewing here

#### Things that are simple(ish) to merge
- v9 bump
- Add support for Deck widgets
- Add `mapWidth` to `Map`
- An alternative `viz` that returns a layer rather than a map
- Surfacing deck.gl `MapView` in `index.tsx` - we're doing this to allow `repeat=true`
- Surface `controller` Python side in `Map`

#### Less simple
- Supporting custom widgets (non deck.gl native js components). It's easy enough to add custom components on the python side, and it's easy enough to split our custom js components into an NPM package. What's unclear to me is the best way to tie a custom js package into `lonboard` and if that's even a good idea.
