[tz] Taiwan (Asia/Taipei) Abbrevation

TZDB uses the abbreviations CST and CDT for Taiwan (Asia/Taipei), CDT last being observed in 1979. According to https://en.wikipedia.org/wiki/Time_in_Taiwan:...the government on Taiwan now favors the term National Standard Time (國家標準時間) as official use. Along with the governmental standard, popular alternatives include Taiwan Standard Time (臺灣標準時間), Taipei Time (臺北時間) and Formosan Time (寶島時間)... Should we update the current abbreviation to either NST or TST? CST doesn't seem right. I'm asking on behalf of a user of moment-timezone (a JS library that imports TZDB) who requested this here: https://github.com/moment/moment-timezone/issues/282 Thanks,Matt
