#2119 Implements GeoRadiusParam.withHash()

[yangbodong22011]

Implements GeoRadiusParam.withHash(), Redis source addReplyLongLong(c, gp->score);, so the score type is long.

I noticed the tip here.

// Do not add WITHHASH since we can't classify result of WITHHASH and WITHDIST,
// and WITHHASH is for debugging purposes

So I distinguish score and distance by type.

if (info instanceof byte[]) {
    // distance
    resp.setDistance(DOUBLE.build(info));
} else if (info instanceof Long) {
    // score
    resp.setScore(LONG.build(info));
}
