Feature request: an option to show the recursive modification date of directories

[noamraph]

Hi, thanks for dua, it's so helpful!

An idea: it would be nice to have an option to show the last modified date of folders. I mean the last modified date of all the files which would be deleted if I delete the folder, not the linux mtime of the folder. This has a significant impact on my decision of whether to remove the folder or not. I guess that since dua already recursively stats all the file in the folder, it should be quite easy to get this data without a performance impact.

Thanks!
