+ Updated the existing download function

+ removed the old download function that was implemented ,
I assumed the original ask was to implement something like
a archiver , in which you repeatedly download the same bunch of files
over and over again with a different file name

+ Realized that the ask was to download to the same folder
again and again ( and also implement a sorting by date with it)

+ This checkin implements a ‘Download all’ version.
+ It can be optimized like the upload too ; Have put some basic data
structures in place . Will iterate on it.
