WASM bindings for the libXMTP rust library

[!INFO] These bindings are not intended to be used directly, use the associated SDK instead.

Setup

1. Install the emscripten toolchain: brew install emscripten. emscripten is used to compile from Rust to WebAssembly.
2. Install LLVM: brew install llvm, and then follow the instructions to add it to your PATH. Emscripten depends on LLVM's Clang (as opposed to Apple's Clang).

Useful commands

• yarn: Installs all dependencies (required before building)
• yarn build: Build a release version of the WASM bindings for the current platform
• yarn lint: Run cargo clippy and fmt checks
• yarn check:macos: Run cargo check for macOS (requires Homebrew and llvm to be installed)

Publishing

To release a new version of the bindings, update the version in package.json with the appropriate semver value and add an entry to the CHANGELOG.md file. Once merged, manually trigger the Release WASM Bindings workflow to build and publish the bindings.
