Title: s2 on s3

Let's create a branch that uses s3 as the backend storage to be able to compare.

This will require:

- [x] 1 level index, switch is already done in the flat branch.
- [ ] 2 flat index levels?
- [x] Combining multiple geometries into a single cell.
- [x] switch dynamo get/put requests to s3
