Support pasting clipboard images using command + v on mac systems

[seems20]

What would you like to be added?

As the title suggests.

Why is this needed?

Currently, on mac systems, only control + v can be used to paste clipboard images, which is inconsistent with mac operation habits.

@seems20 Thanks for the feedback. qwencode currently supports pasting images using cmd+v/crtl+v on macOS. However, whether cmd+v works depends on the command-line application you're using (cmd+v, as the default paste key, is blocked by some command-line applications). Therefore, if you cannot use cmd+v in your command line, please use crtl+v instead.
