feature: Add clear clipboard history button

[muhammadyusuf-kurbonov]

Is your feature request related to a problem? Please describe.
I have increased the history size to 20. After work, I don't want to see these texts anymore 😃 and wanna clear the whole history. But I couldn't find the button Clear clipboard history. There is solution to remove each item, but it is less comfortable

Describe the solution you'd like
Add button Clear on the right top for panoWindow

Describe alternatives you've considered
Manually remove each item - too much work.

Additional context
Great and awesome project. And perfect code (I'm a developer too 👍 ). Good luck ⭐ * Infinity

Hi, it already has this functionality. You can clear all history by going to the Pano extension settings.
