ls/ls-url: introduce --size

I really need it only for studio right now, but this is really nice to have in a daily life as well. E.g. ``` $ dvc ls-url . --size 108 Metadata-and-Results.dvc 97 AudioMP3.dvc 97 AudioWAV.dvc 12181 README.md 54 .gitignore 168 .gitattributes 99 VideoFlash.dvc 312 LICENSE.txt 139 .dvcignore 96 AudioMP3 96 Asset 192 .dvc 64 Metadata-and-Results 64 AudioWAV 192 Scripts 64 VideoFlash 384 .git 96 .vscode ``` ``` $ dvc list . --size 139 .dvcignore 168 .gitattributes 54 .gitignore 96 .vscode 96 Asset 96 AudioMP3 97 AudioMP3.dvc 64 AudioWAV 97 AudioWAV.dvc 312 LICENSE.txt 64 Metadata-and-Results 108 Metadata-and-Results.dvc 12181 README.md 192 Scripts 64 VideoFlash 99 VideoFlash.dvc ```
