+ Creating a dictionary of fname:year_of_creation

+ AWS S3 APIs do not have the time(year) at which the files were
created.

+ Adding a data structure to keep track of this. Similar to the hash
map that was used to keep track of last_modified_time , a new file of
name “creation_time.txt” will keep track of ctime of all files that are
being uploaded

+ A little bit of string-fu on the time value directly returns the year
of creation.

Test: Printing the creation_time_dict and this is how it looks(upload
continues to work as before)
