Function onceNAsync

onceNAsync<T extends (...args: any[]) => Promise<any>>(
n: number,
fn: T,
): (...args: Parameters<T>) => Promise<undefined | ReturnType<T>>
Runs an async function at most n times. Subsequent calls return the result of the last invocation.

The returned function caches the result of each invocation and ensures fn is called no more than n times. After n calls, the cached result is returned.
Type Parameters
- T extends (...args: any[]) => Promise<any>
  The type of the async function to be invoked.
Parameters
- n: number
  The maximum number of times to call fn.
- fn: T
  The async function to invoke.
Returns (...args: Parameters<T>) => Promise<undefined | ReturnType<T>>
A function that calls fn up to n times and returns a Promise of the result.

Example
```
const limited = onceNAsync(2, async () => {
  console.log("Running");
  return 42;
});
await limited(); // logs "Running", returns 42
await limited(); // logs "Running", returns 42
await limited(); // returns 42, does not log
```
