wasm support for typescript bindings

[aki-mizu]

Describe the enhancement

uniffi-bindgen-react-native has recently added wasm support
https://github.com/jhugman/uniffi-bindgen-react-native/releases/tag/0.29.3-0
Use case

Why use uniffi-bindgen-react-native instead of wasm-bindgen?
uniffi-bindgen-react-native generates a wasm-bindgen crate, from uniffi annotations.
when you come to use your Rust crate in another context (say, from Python, or Kotlin, or React Native), then you can generate FFIs for those platforms, all with the same uniffi annotations.
Additional context

Now uniffi-bindgen-react-native supports WASM, the React Native no longer seems appropriate. In the near future, we'll change the name to uniffi-bindgen-javascript. Backwards compatibility will be ensured.

Above are reference from their repo

If this can be achieved, then maybe we no longer need to maintain separate nostr-sdk-js repo
I tried to add ubrn build web --and-generate into https://github.com/rust-nostr/nostr-sdk-react-native
But it does not work out of the box due to nostr-sdk-ffi does not yet support wasm target

Awesome!

I'm currently using uniffi 0.28.3, because https://github.com/NordSecurity/uniffi-bindgen-cs requires it. I can see if it's easy to port the WASM support to uniffi-bindgen-react-native v0.28.3, otherwise I'll wait that uniffi-bindgen-cs bumps uniffi to 0.29.3

Just checked and uniffi 0.28.3 doesn't support WASM so we have to wait that uniffi-bindgen-cs bumps to uniffi v0.29.3
