pzem-004t v3 (pzemac) timeout option #1694

When the PZEM-004T V3 loses AC power it stops responding to esphome due to it requiring AC power. It would be handy to have a timeout option that either zeros out all the sensor values or sets them to unavailable if the sensor does not respond.

This would be very useful to detect AC power failures without adding additional components. Especially when the ESP has its own power source.
