```
ControlNotificationStream.dropFirst(_:)(count: Int) -> AsyncDropFirstSequence<Self>
```

Omits a specified number of elements from the base asynchronous sequence, then passes through all remaining elements.

Use `dropFirst(_:)` when you want to drop the first *n* elements from the
base sequence and pass through the remaining elements.

In this example, an asynchronous sequence called `Counter` produces `Int`
values from `1` to `10`. The `dropFirst(_:)` method causes the modified
sequence to ignore the values `1` through `3`, and instead emit `4` through `10`:

    for await number in Counter(howHigh: 10).dropFirst(3) {
        print(number, terminator: " ")
    }
    // Prints "4 5 6 7 8 9 10 "

If the number of elements to drop exceeds the number of elements in the
sequence, the result is an empty sequence.

- Parameter count: The number of elements to drop from the beginning of
  the sequence. `count` must be greater than or equal to zero.
- Returns: An asynchronous sequence that drops the first `count`
  elements from the base sequence.
