Alternative Go Client

[Freeaqingme]

Howdy,

I wanted to integrate @Coinigy ( https://www.coinigy.com ), and therefore would also need SocketCluster support in Go. I initially started off with the provided Golang client, but its API appears to be a literal clone of the JS client. Now I understand this can be up to a certain extent desirable, but at the end of the day Go != Javascript.

As such, I decided to write my own implementation, which can be found here: https://github.com/Freeaqingme/go-socketcluster-client

Because Coinigy does not use JWT I did not implement that, but the other features have been implemented.

Perhaps this is worth considering to add as a second Go implementation?
