Cancel any live orders found on connect

More or less just to avoid orders the user wasn't aware of from
persisting until we get "open order relaying" through the ems working.

Some further fixes which required a new `reqids2txids` map which keeps
track of which `kraken` "txid" is mapped to our `reqid: int`; mainly
this was needed for cancel requests which require knowing the underlying
`txid`s (since apparently kraken doesn't keep track of the "reqid"  we
pass it). Pass the ws instance into `handle_order_updates()` to enable
the cancelling orders on startup. Don't key error on unknown `reqid`
values (for eg. when receiving historical trade events on startup).
Handle cancel requests first in the ems side loop.
