Description

I have an implementation of this in Datsync (here), and I'd really rather have it just be a function in datascript.core if you're amenable. More or less, it creates a new database from the old datoms and the updated schema.

There's a question about what the should be sent to listeners when this happens. It could perhaps be a more or less empty transaction report with keys :schema-changes, :new-schema and :old-schema, perhaps.

Happy to clean this up and PR if you like.

Research direction

Start with the Datsync implementation at src/dat/sync/client.cljc around line 437, then compare it with the datascript.core API. Clarify how rebuilding a database from old datoms and an updated schema should report to listeners, including the proposed :schema-changes, :new-schema, and :old-schema keys. Done means an agreed function and transaction-report behavior are defined for a pull request.
