Unicode Label Support

• [X] I have searched the Supervision issues and found no similar feature requests.

Description

I'm using supervision with unicode label data. When I assign unicode label information to the labels parameter, supervision only draw strange squares instead of label text. After search for a moment, I noticed that cv2 only supports ascii text when using putText. The square block is created by cv2 not supervision itself.

Use case

Supervision is good and love it so much. There are many label information not in native ascii. I think support it would be good.

Additional

I found a work around way to solve the issue is to use PIL to draw the text with user defined truetype font. By this way, I think supervision could avoid the GPL license problem.

Hi, @Ucag 👋🏻! Thanks a lot for your interest in supervision 🙏🏻 ! Adding support for PIL as a text rendering engine is 100% on my TODO list. I really wan to do it but I'm quite busy so I doubt I will be able in upcoming weeks :/

I've done a primitive version using PIL to render text with unicode support, If you don't mind, I would like to PR.
