Add Logo Watermark functionality

[BettaiebMohamed]

I would like to request the addition of a logo watermark functionality to Open Camera. This feature would allow users to overlay a custom logo on their photos and videos directly within the app.

Proposed functionality :
Logo Upload (to be put in the middle ) / and If it is possible Positioning and Scaling

Thank you for considering this feature request. Open Camera is a fantastic tool, and I believe this addition will make it even more versatile and user-friendly.

Best regards,
Mohamed
