Potential issue with Maximum() on sroar

sroar.go

package main

import (
	"fmt"

	"github.com/RoaringBitmap/roaring"
	"github.com/dgraph-io/sroar"
)

func main() {
	b := sroar.NewBitmap()
	b.Set(1)
	b.Set(100)
	b.Set(100000)
	fmt.Println(b.GetCardinality(), b.Minimum(), b.Maximum()) // 3 1 100

	b2 := roaring.NewBitmap()
	b2.Add(1)
	b2.Add(100)
	b2.Add(100000)
	fmt.Println(b2.GetCardinality(), b2.Minimum(), b2.Maximum()) // 3 1 100000
}
