Run in worker process

[HerbCaudill]

Enable running Cevitxe's StoreManager entirely in a web worker process. See HerbCaudill/react-redux-worker for a starting point.

All the Automerge, local storage and sync components would live in the worker, thus freeing the UI context of all the expensive overhead of the system.

We'll need a coarse-grained query API to query and retrieve a view of a set of rows, aggregate information, etc. In order of priority:

• order + range / count
• filter
• aggregation, projection, etc. (might be entirely out of scope)
