This sets up a new way to build the WebAssembly modules with SQLite and the PowerSync core extension. It clones the upstream
sqlite3.dartrepository at a given tag and applies a patch to the build scripts to include the extension. The resulting WebAssembly files are also published with the workers when we tag a powersync release.The
setup_web.dartscript will use releases from this repository (and expect wasm files there) starting with the next minor version, 1.12.0. This gives us the opportunity to prepare a patch release to test the publishing workflow.Additionally, I've set up a small npm package that allows us to publish the compiled WebAssembly modules to npm. This allows us to use npm-aware CDNs to deliver the WebAssembly assets (useful for e.g. FlutterFlow users that can't include
.wasmassets in test mode).
