Murmur text is overlapped by the iOS status bar text

Hi there,

It's a great library. Thank you for your work.

I am experiencing the following issue:

When I display a Murmur the iOS status bar text is not overlapped by the Murmur text. It's kind of a merged info. I am using Xcode 12.0.1 and iPhone 8 device/simulator. Both iOS 13.7 and 14.0.1 produces the issue.

It's happening in both Light and Dark mode. Please let me know if I am doing something wrong. Thanks!

```
let murmur = Murmur(title: "Updating...", backgroundColor: .orange, titleColor: .white)
Whisper.show(whistle: murmur, action: .present)
```
