python3.5.0 incompatibility

[anthraxx]

Would it be possible to make this library functional for python3?
The python2 tests are running fine, however if I invoke it with python 3.5.0, I get a ValueError:

python3:

This requires bytes object

tlsh/py_ext/tlshmodule.cpp

Line 181 in dafea28

if (PyBytes_AsStringAndSize(arg, &str, &len) == -1) {

This create a str object

tlsh/py_ext/tlshmodule.cpp

Line 117 in dafea28

"Get the computed TLSH as a string object containing only hexadecimal digits."

tlsh/py_ext/tlshmodule.cpp

Line 252 in dafea28

return Py_BuildValue("s", hash);

and finally this test passes the str object to a function that requires bytes object:

tlsh/py_ext/test.py

Line 39 in dafea28

h3.fromTlshStr(hex2)
