Fix bytes parsing when used with python-future

[jameshilliard]

This allows bencoder.pyx to be used with python-future, if the bytes type is enforced I get this error:

  File "bencoder.pyx", line 174, in bencoder.bencode
  File "bencoder.pyx", line 106, in bencoder.encode
  File "stringsource", line 67, in cfunc.to_py.__Pyx_CFunc_object____object____list___to_py.wrap
  File "bencoder.pyx", line 155, in bencoder.encode_dict

TypeError: Expected bytes, got newbytes
