For those who might find it helpful. Applicable to python3 only

If we look closely to these tables -> columns for erlang binary() to python bytes() for [python3 only] vise versa.
This basically means that arguments of str() data type in erlang sent over to python functions will be converted to bytes() in python3.
So for python functions expecting arguments of str() data type, do not forget to convert the received arguments back to python string before using.

# gist ref
decoded_args = locals()
for arg_name, arg_value in locals().items():
if isinstance(arg_value, bytes):
decoded_args[arg_name] = arg_value.decode("utf-8")

Cut a new release for hex

I know there haven't been a lot of changes since 2017, but the OTP-21 support at least seems big enough to bump the version.
