* Deribit: Subscription Pairs support
* Websocket: Accept nil lists for checkSubscriptions
If the user passes in a nil (implicitly empty) list, we would not panic.
Therefore the burden of correctness about that data lies with them.
The list of subscriptions is empty, and that's okay, and possibly

* Websocket: Add context to NilPointer errors
* Subscriptions: Add context to nil errors

* Websockets: Move Subscription to its own package
This allows the small type to be imported from both `config` and from
`stream` without an import cycle, so we don't have to repeat ourselves

This was being mis-used through much of the code, and since we're
already touching everything, we might as well fix it

Use isolated test instance for `TestGetOpenInterest`.
`TestGetOpenInterest` would occassionally change pairs before
GenerateDefault Subs.
