issue longld#177 fixes applied

1.fix SyntaxWarning

adding r to the strings
eg

 p = re.compile(r"(.*)\[(.*)\]") # DWORD PTR [esi+eax*1]

to make it raw string, pull request longld#178 fixes this.

2.fix six.moves not found

using

pip install six # old 
apt install python-six # debian
pacman -S python-six # arch linux

and remove the six.py in the lib/
so it uses the global ones and not the local one found in lib
