func NewV7FromReader(r io.Reader) (UUID, error) {
	uuid, err := NewRandomFromReader(r)
	if err != nil {
		return uuid, err
	}

	makeV7(uuid[:])
	return uuid, nil
}

// makeV7 fill 48 bits time (uuid[0] - uuid[5]), set version b0111 (uuid[6])
// uuid[8] already has the right version number (Variant is 10)
