ASASSN-17es: updated superhump periods

     Josch Hambsch and Pavol Dubovsky have reported further observations.
I reported the period of early superhumps is 0.063-0.066 d, but the object
showed clear ordinary superhumps with a period of 0.058 d. I reanalyzed
the early superhump period, then the updated early superhump period is
0.05709 (4) d.
     The O-C diagram shows stage A-B transitions. The period of stage A and B
is 0.05885 (5) d and 0.05788 (3) d, respectively. By using these period, the
mass ratio is estimated to be 0.077-0.086.
     Further observations are encouraged.
