   tested ACK e83699a626b8a41c8fb9d0450e14e06a29a98bb8

   following existing directions: Error: Invalid port specified in -zmqpubrawtx: 'ipc:///tmp/bitcoind.tx.raw' updated directions work 👍

   Ran bitcoind with both example endpoints.

   ipc:///tmp/bitcoind.tx.raw: exits with “invalid port specified” unix:/tmp/bitcoind.tx.raw: node starts cleanly

   interface_zmq.py passed

   ACK e83699a
