CancelOrders

Hi

I am attempting to `CancelOrders`, but it doesn't work.

Can someone perhaps give me an example?

This is my code:

`await kraken.api("CancelOrder", {"txid":"hidden-hidden-hidden"});`

Here is the Error:

`
...kraken-api/kraken.js:54
                throw new Error(error.join(', '));
                      ^
Error: Order:Unknown order
`
