Encode an EIP-712_ message.
EIP-712 is the "structured data" approach (ie~ version 1 of an EIP-191 message).
Supply the message as exactly one of the three arguments:
- primitive, as a dict that defines the structured data
- primitive, as bytes
- text, as a json-encoded string
- hexstr, as a hex-encoded (json-encoded) string
.. WARNING:: Note that this code has not gone through an external audit, and
the test cases are incomplete.
Also, watch for updates to the format, as the EIP is still in DRAFT.
:param primitive: the binary message to be signed
:type primitive: bytes or int or Mapping (eg~ dict )

:param text: the message as a series of unicode characters (a normal Py3 str)
