Reversed heartbeat #47
Description
Hi,
thank you so much for the readme: it contains invaluable information!
Regarding the heartbeat, it seems sufficient to just reply to the PINGs sent from (and to) Tr@n$p0rt-0 with a PONG with the same transport (example in my repo: https://github.com/oliverpool/go-chromecast/blob/master/command/heartbeat/heartbeat.go#L14)
This way you don't have to guess the right interval to send your ping: just wait for a ping and reply to it :-)
