SwiftWasm Asyncify Sample

Showcase SwiftWasm code that's impossible to accomplish without Asyncify method:

• Sleeping inside synchronous code, without resorting to callback (or Swift Next's async/await).
• An initializer (which needs to return synchronously) that depends on asynchronous code from the outside world.

Prerequisites

• Install the SwiftWasm toolchain
• Set SwiftWasm's swift as default or edit the swift command in build.sh.
• Install the Binaryen toolchain (we'll use the wasm-opt tool from there).
• Set Binaryen's /bin in PATH or edit the wasm-opt command in build.sh.
