fs.writeSync() only supports string input, fs.readSync() only support 4-5 argument version

[guest271314]

I'm testing scriptc compilation of Native Messaging hosts I've already written and tested using other tools and environments.

Straight up TypeScript https://github.com/guest271314/NativeMessagingHosts/blob/main/nm_typescript.ts input compilation fails.

Using Node.js fs.readSync() https://nodejs.org/api/fs.html#fsreadsyncfd-buffer-options and fs.writeSync() https://nodejs.org/api/fs.html#fswritesyncfd-buffer-offset-length-position, which work using js2wasm fails, too. Notice the error messages. There's more than one signature for readSync() and writeSync(); scriptc is only recognizing the 4-5 argument version and is expecting a string exclusively to writeSync() https://github.com/guest271314/js2/blob/main/examples/native-messaging/nm_js2wasm_node_fs.ts, https://github.com/guest271314/js2/blob/main/examples/native-messaging/nm_js2wasm_sync_framing.ts. After adjusting readSync() to the 4-5 argument version readSync(0, buf, 0, buf.length), writeSync() still fails, expecting only a string.
