Kraken: Fix wsCancelOrders not erroring with order id

[gbjk]

We were using the "cancel many" facility of the Kraken api. However since that doesn't actually report errors individually, it seems saner to just multiplex over it. We were going to get N+ responses anyway. Might as well send N+ requests

One thing I'm unhappy about is the change of Key/Secret for this to work. I really don't like that there's special values for the auth values which get silently ignored, such as Test, Mock, Key, Secret, etc. So I've ended up using something adhoc, and putting a require in the test to ensure it's obvious if the auth-conn isn't connected.

Type of change

• [x] Bug fix (non-breaking change which fixes an issue)

How has this been tested

• [x] go test ./... -race
• [x] golangci-lint run
• [x] TestWsCancelOrders

I'm not liking those failures in kraken's TestWsOpenOrders; Sniffing it now

[gbjk]

TestWsOpenOrders errors were unrelated. This is good to review.

Already in the next upcoming branch.

I've got significant testing of Subscribe in there without mocking, so I'm on the fence about adding a mock for it if we don't have to ( perversely ).

Anyway, Let's touch on this when that PR lands.
