trash-empty empty only PWD trashcan (like trash-restore does)

[Andrew15-5]

Is your feature request related to a problem? Please describe.

I use lf with trash-cli and I can't empty only one of many trashcans. But I can empty all of them or empty all of them from all users or empty --trash-dir which wants a valid trashcan path (I don't know how to get it without making a whole script file).

Describe the solution you'd like
I want trash-empty to work as the trash-restore command, which will automatically only list files from the current trashcan. Or add an option like --local-trash-dir.

Describe alternatives you've considered

I can in theory whip up a script that will give me a valid trashcan path and then use it with --trash-dir option, but it probably
wouldn't be concise and readable, so I don't think that would be a great idea.
