Bump @web5/dids and add DID Resolver cache (#685)

This PR will:
- Bump the `@web5/dids` package from `0.3.0` to `0.4.0`.
- Adds a DID resolver cache to the default instantiate of a `Dwn`. The
cache is a TTL cache with a 15 minute default timeout. It uses a
persistent LevelDB cache which will keep approximately 8,000 DID
documents in an in-memory cache before flushing to disk. Since the cache
entries are persisted to disk, they will survive process restarts.
- Bump `@tbd54566975/dwn-sdk-js` to `0.2.17` so it can be published to
NPM Registry.
