[feature] v7 testnet support

[moneroexamples]

Do you have demo running on v7 testnet? I think current demo https://amiuhle.github.io/kasisto/#/ is for v6 testnet only?

[amiuhle]

Yes, that's for v6 testnet only, because I expect people to use a mobile wallet to test, which are running release binaries and therefore use the v6 testnet.

You can set up your own v7 testnet version: https://github.com/amiuhle/kasisto/blob/master/docs/server-setup.md

Thanks, I will try to setup it for myself.
