Display network name in chia show

[speedmann]

The gui shows to which network you are connected.
Can we have the same for the CLI?

For testing i just added

            net_name = await client.fetch("get_network_info", {})
            print(f"Network name {net_name}")

just above difficulty = blockchain_state["difficulty"]

I'm quiet sure this is not the intended way to do so, but it's a starting point.

Do we have any chance to get this small feature?
