[FEATURE] Add a logo for rembg

[Jack-Development]

Is your feature request related to a problem? Please describe. I am currently using rembg within many applications and presenting the usage of it. As part of that I produce diagrams to represent this process, and write "rembg".

Describe the solution you'd like I think it would not only be beneficial to users, but to the project to have a logo that can be used as a shorthand in marketing or advertising of the system.

Describe alternatives you've considered As I have said currently I simply write the name of the project.
