py-amqp: updated to 2.4.1

2.4.1:
- To avoid breaking the API basic_consume() now returns the consumer tag
  instead of a tuple when nowait is True.
- Fix crash in basic_publish when broker does not support connection.blocked
  capability.
- read_frame() is now Python 3 compatible for large payloads.
- Support float read_timeout/write_timeout.
- Always treat SSLError timeouts as socket timeouts.
- Treat EWOULDBLOCK as timeout.
  This fixes a regression on Windows from 2.4.0.
