bencode for Python2 and Python3
Source code adopted from https://pypi.org/project/bencode/ and https://pypi.org/project/BitTorrent-bencode/.
For Python3, argument for bdecode() has changed to bytes, bencode() has changed to return bytes.
String is decoded as raw bytes (no further decoding to string with UTF-8 or other encoding) and encoded as bytes with UTF-8.
