Update IANA timezone db to 2020c


     Fiji starts DST later than usual, on 2020-12-20.

   Changes to future timestamps

     Fiji will start DST on 2020-12-20, instead of 2020-11-08 as
     previously predicted.  DST will still end on 2021-01-17.
     (Thanks to Raymond Kumar and Alan Mintz.)  Assume for now that
     the later-than-usual start date is a one-time departure from the
     recent pattern.

Either in JS console in Chrome or v8 should work like these:
const df1 = new Intl.DateTimeFormat("en",{timeZone: "Pacific/Fiji", timeStyle: "long", dateStyle: "long"})
const d3= new Date("2020-12-19T00:00:00.000Z");
const d4= new Date("2020-12-20T00:00:00.000Z");


Before the change:
"December 19, 2020 at 1:00:00 PM GMT+13"
"December 20, 2020 at 1:00:00 PM GMT+13"

After the change:
"December 19, 2020 at 12:00:00 PM GMT+12"
"December 20, 2020 at 1:00:00 PM GMT+13"
