Support Raycast's Hyper key

[franky47]

Hi, I bought this app wanting to do a presentation on Raycast, which provides a feature called the Hyper key, which emits all four modifier keys at once (⇧⌃⌥⌘) when pressing the Caps Lock key.

Keyscreen however only detects the ⌘ key modifier in that case, it would be nice to detect all four and display Raycast's Hyper key icon.
