/**
* Function that returns a `Promise` that `await`s an `async` function's completion.
*
* @param {Object} [arg={}] The argument to be destructured.
* @param {function} [arg.asyncFn=AwaitingPromise.DEFAULT_FN] An `async` function whose completion is to be `await`ed.
* Defaults to a no-op function.
* @param {boolean} [arg.positive=true] If truey, the returned `Promise` will resolve if `asyncFn` does not throw, and will reject with the error that `asyncFn` throws.
* If falsey, the returned `Promise` will reject with parameter `err`'s value if `asyncFn` does not throw, and will resolve with the error that `asyncFn` throws.
