Fixed: DownloadUsage.py invalid syntax, requirements.txt issues

[james-flynn-ie]

Adding fixes for the DownloadUsage.py script, as it failed to execute due to requirements.txt and invalid syntax errors:

• Fixed print statement declarations

  File ".\DownloadUsage.py", line 23
    print "Parsing Access Log..."
          ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("Parsing Access Log...")?

  File ".\DownloadUsage.py", line 39
    print Fore.RED + "Could not find",(notfound),"artifacts(most likely deleted)"
          ^
SyntaxError: invalid syntax

• Removed duplicate import statement (colorama)
• Replaced 'ur' string type with the synonym 'r' (which is compatible with both Py2 and Py3).

  File ".\DownloadUsage.py", line 26
    p = re.compile(ur'(\d*)-(\d*-\d*\d*......)(........)(.*])(.*)(:)(.*)(for)(.)(.*)(\/)(.*)(\.)')
                     ^
SyntaxError: invalid syntax

• Removed dependencies from requirements.txt which are installed as part of Python and not found on Pip:

   ERROR: Could not find a version that satisfies the requirement sys
   ERROR: No matching distribution found for sys
   ERROR: Could not find a version that satisfies the requirement re
   ERROR: No matching distribution found for re
   ERROR: Could not find a version that satisfies the requirement json
   ERROR: No matching distribution found for json

Changes verified on Python 3.8.2.
