When Typescript 5.2 is released, consider updating and using the new `using` keyword.

[georgestagg]

The new using keyword could give us a nicer way to manage R object memory. What is currently,

try {
  const foo = await webR.evalR('foo');
} finally {
  webR.destroy(foo);
}

could become something like,

{
  await using foo = webR.evalR('foo');
  // Do something with foo...
} // Automatically destroyed!

The finaliser is defined in a special symbol property of the object foo, so IIUC we would "just" need to include a new property in the generic RObject proxy object hooks.
