chore: Update Elsa dependency and correct import paths

- Updated Elsa dependency branch from `sync_index_map` to `sync_frozen`.
- the elsa import now matches Manishearth/elsa#67 and thus a more recent version of elsa.

- Corrected the  import statement in `hash.rs`.
- Modified import paths for `FrozenIndexSet` in the `store.rs` and `lem/store.rs` files.
