SD card files sorting on the printer screen

[TioSam13]

First of all, thanks for the wonderfull work on our firmware, it's a game changer with more options than creality stock for sure.

I would like to request a extra option on the configuration menu to choose between alphabetic and last modified files on the printer screen. Currently, we are locked with alphabetic order wich is ok, but lot's of times we have Stl's with similar file names

Add an option on the advanced menu to choose between alphabetical and last modified files. Prusa already got this option compiled on their firmware as seen in the 2 images bellow
