Add delete option to upload command

[kosli]

It would be great if there would be a delete option when using the upload command, so that a successful upload (or check with online version) would delete the local copy of the file. This would reduce the work on cleaning up local directories where the images have been uploaded and where only unsupported filetypes will be left in the directories.

It's a long waiting request.
I was reluctant to implement it because Immich-go could be buggy.
Maybe I can reconsider it

I believe this could be a valuable feature. Instead of deleting the files, the option could involve moving successfully uploaded files to a different directory or a separate folder.

Same request here. Often the datasets have duplicates and snapshots so it isn't an issue. It can be a tech workaround foolsafe implementation. Much thanks!
