[P110] Handshake failing in latest firmware

[achetronic]

Hello there. First, congratulations for this amazing project. It's being used as library inside https://github.com/achetronic/autoheater/

With the latest version of the firmware on P110 plugs (updated not in purpose, but forgot disable automatic updates) I got the following message:

panic: interface conversion: interface {} is nil, not map[string]interface {}

goroutine 1 [running]:
github.com/richardjennings/tapo/pkg/tapo.(*Tapo).Handshake(0xc000146000)

I assume this is caused by a change on Tapo API spec. Do you know something about? :)

Tapo changed the protocol to KLAP. See here: evcc-io/evcc#10461

@arigon @TazerReloaded Thank you for guiding me to the problem. I supposed it but needed the exact names

The library maintainer does not seem to be maintaining this anymore, so finally I did some research, tests and ports and got it working https://github.com/achetronic/tapogo

Mine is only supporting the latest KLAP protocol. I arranged it in a reusable way just in case the maintainer of this one wants to introduce KLAP on this. Hope my research will be useful for everyone 🙂
