add filesystem time deletion to TrashItem

[ramsteak]

I'd like if the filesystem time of deletion was accessible for TrashItem elements, as in windows the std::fs times are not in i64 UNIX timestamp but in u64 windows filetime, and calculating differences requires converting back and forth between the two formats

Thanks for reporting. Unifying the representation of time across platforms seems like a valuable addition, thanks for sharing.

I made a pull request #79 to add this attribute

Deleted PR, this change would actually make it harder to work cross-platform and would require checks for windows and unix separately
