This is set pretty low right now, which can result in slower ethernet throughput. I had it up towards the 30MHz range, but was seeing data corruption, so I dropped it down. Given the long ribbon cable, I'm inclined to leave this low until we have a need to bump it up.

Ack. I checked SPI modes. Agreed to stay at 1 MHz until somebody from the HW development confirms SI and max speed. There are the knobs of tuning the IO speed on the µC, but I don't expect much and wouldn't dive into it.

This PR addresses #7 by adding initial support of MQTT telemetry reporting via the W5500 TCP/IP stack.
