[CHANGE] Implement as a new option: LastModificationDate (mtime)

[steph-nb]

(Copy of codeberg.org issue nr. 5)

Hi Steffen,

when experimenting with problematic hd-images containing identical files at several distinct paths - which I can easily detect already by sorting by hash-value, what is great already (!) - I thought that as an additional output-option the mtime of the files would be great.
We then could easily detect the oldest copy of identical files, and only treat that specific copy.

What do you think, could you implement mtime in a next version?

Many thanks and BR,
Stephan

Added it by using https://github.com/djherbis/times Please check supported times here https://github.com/djherbis/times#supported-times

It is btw not an option, all dates are added to the output when available. If not the column is empty.
