@gmaclennan anything else that you think should be updated in this PR?

I don't think so. I already did all the work for publishing typescript types, and have done a test publish as a module. It is currently published as @mapeo/core@9.0.0-alpha.0, and only the alpha npm dist tag points to it - the latest dist tag points to v8.6.2 (we should keep it like that for now). To install do npm i @mapeo/core@alpha or use the specific version npm i @mapeo/core@9.0.0-alpha.0

Maybe remove the MapeoProject export now? Not sure it is needed?

Feel like it'd be useful to keep if we're talking about general usage of this library, but if we're not concerned about that right now then that's okay too

EDIT: guess one could still import the project via import { MapeoProject } from '@mapeo/core/src/mapeo-project.js' right?
