ping360 ethernet support

Reports that ping360 is not automatically connecting with companion when connected by ethernet.
investigate.

If Ping360 is configured with ethernet connection internally, it should work with a normal router or a switch.

What can happen is that Ping-Viewer detects Ping360 through a switch and shows a “yellow circle” in Ping-Viewer saying that something may be wrong, and if you hover the mouse over it a message you inform that the network subnet is not compatible:

It should be fixed if the user enables the DHCP server on companion or configure Ping360 to a static IP address before connecting.
What we could do is to broadcast a setStaticIPAddress message but this may brake any case where multiple sonars/compatible sensors are in the network.

But you'll see Ping-Viewer detecting the sonar, no matter what. If Ping-Viewer does not detect it, it's probably a hardware issue.

I tested the Ping360 connection with companion in DHCP Server mode and I got the following result:

So even with companion in DHCP server mode the device wasn't configured with a correct IP address on a compatible subnet. I attempted to set a static address by clicking the gear icon but the settings would not save after multiple attempts.
