bytesare immutable andPyBytes_AsStringAndSizereturns pointer to the buffer. Similarlystrare immutable andPyUnicode_AsUTF8AndSizereturns a pointer to cached buffer that lives as long as the object.Currently we create a new Erlang binary, which means copying the data once. This PR changes it such that we create resource around the Python objects and create a zero-copy resource binary term.
