Add hypotnuse method to Distance

[MrTinker64]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I have to do distance.in(distanceUnit) followed by some math and then unit.of(resultOfMyMath)

Describe the solution you'd like
The same way there is .div and .plus methods for Distance I would like a .hypot(otherDistance) method. Using the plus method at Line 59 of Distance as an example I would write it like this:

@Override
default Distance hypot(Measure<? extends DistanceUnit> other) {
  return (Distance) unit().ofBaseUnits(Math.hypot(baseUnitMagnitude() + other.baseUnitMagnitude()));
}

Additional context
Here's what I'm currently using as a work around in my code:

public static Distance hypot(Distance a, Distance b) {
  return a.unit().of(Math.hypot(a.magnitude(), b.magnitude()));
}

IMO this doesn't sound like it should be an instance method. Reading a.hypot(b) it's very unclear what operation it's meant to be performing on a. I'm not sure how one would explain/document this as an operation either.

On the other hand a static method hypot(a, b) would be significantly easier to explain.

So instead it would be Distance.hypot(a, b)? That sounds good to me!
