> When the Int64Builder is used in a context without BigNum, appending two numbers combines them into a single Int64:
> {code}
> > v = Arrow.Builder.new({type: new Arrow.Int64()}).append(1).append(2).finish().toVector()
> > v.get(0)
> Int32Array [ 1, 2 ]
> {code}
> Whereas the same process with BigNum creates two new Int64s.
