SyntaxWarning invalid escape sequence (Python3.12.3) * with potential fix.

[fugaw1]

In python3.12.3 there's some new errors while using ctfr.py:

/home/sous/programs/ctfr/other:27: SyntaxWarning: invalid escape sequence '\ '
  b = '''
/home/sous/programs/ctfr/other:40: SyntaxWarning: invalid escape sequence '\.'
  return re.sub('.*www\.','',target,1).split('/')[0].strip()

A simple fix is adding the r to convert Python string literals:

def banner():
        global version
        b = r'''
          ____ _____ _____ ____  
         / ___|_   _|  ___|  _ \ 
        | |     | | | |_  | |_) |
        | |___  | | |  _| |  _ < 
         \____| |_| |_|   |_| \_\

     Version {v} - Hey don't miss AXFR!

        '''.format(v=version)
        print(b)

def clear_url(target):
        return re.sub(r'.*www\.','',target,1).split('/')[0].strip()

Then no errors:

Thanks!
