WOL Switch - Change parameters (# of pings)

Feature Requests
1

Hey there, I noticed in the WOL Switch that it only sends one ping which is sometimes resulting in false ‘off’ on some wifi devices. Could this be exposed through configuration so it sends more than one ping?

ping_cmd = [‘ping’, ‘-c’, ‘1’, ‘-W’,
str(DEFAULT_PING_TIMEOUT), str(self._host)]

Love Home Assistant and this community!
Cheers,
