More cruise speed for Barge

[Haste]

At 200 cruise speed, the Barge would move ~3.43 times as much cargo on cruise (per "unit of time") as a 5k. This would be exceedingly broken. Unfortunately having 30,000 cargo means you need massive restrictions to not utterly break the economy. I think the Barge is in a healthy state right now, clearly having advantages (particularly a jumpdrive slot) and disadvantages, without breaking the economy. It's seeing a good bit of use but is no longer the go-to meta powertrading ship. I'd rather leave it be.
