Support Dynamic Workers

### Problem Statement

Dynamic Workers were added to sandbox code you can't trust.

Some more info for Dynamic Workers:
Blog post: https://blog.cloudflare.com/dynamic-workers/
Dev docs: https://developers.cloudflare.com/dynamic-workers/
Examples you can get started with: https://developers.cloudflare.com/dynamic-workers/getting-started/#try-it-out
Worker-bundler: https://www.npmjs.com/package/@cloudflare/worker-bundler

Currently I assume that nothing would happen once this spins up and they won't get instrumented.

### Solution Brainstorm

We would need at least a new span around the newly spawned worker, to see how long this worker runs.

We could also add an additional option to instrument the dynamic worker as well.
