Stop the idle loop in Main from polling every millisecond - #20

The loop that waits for Program.Exit used Task.Delay(1) followed by Task.Yield(), which woke the thread pool about a thousand times a second. An idle atlasd (no clients connected) used about 32% of a core on macOS/.NET 10; with a 250ms delay it uses about 1.3%. Shutdown reacts within 250ms.

NullTimer sends SID_NULL every 60 seconds and PingTimer sends SID_PING every 180 seconds, but both fired every 100ms, and PingTimer reads a setting and allocates a message and a Random on every tick. A one second period is still far finer than the intervals they enforce. Idle atlasd (no clients, 250ms idle loop) went from about 1.5% of a core to about 0.5%.
