Runs a Tailscale client in the browser (via a WebAssembly build of the wasm package) and allows SSH access to machines. The wasm package exports a newIPN function, which returns a simple JS object with methods like start(), login(), logout() and ssh(). The golang.org/x/crypto/ssh package is used for the SSH client. Terminal emulation and QR code renedring is done via NPM packages (xterm and qrcode respectively), thus we also need a JS toolchain that can install and bundle them. Yarn is used for installation, and esbuild handles loading them and bundling for production serving. Updates #3157 Signed-off-by: Mihai Parparita <mihai@tailscale.com>
