[tz] Turks & Caicos to resume DST; details unclear

According to an article published in the Bahamas website Magnetic Media, the 
cabinet of Turks & Caicos decided on Thursday to resume the practice of daylight 
saving time starting in 2018. The article does not give enough details to update 
the database (it confuses summer with winter time, among other things). My guess 
is that Turks & Caicos will revert to its pre-2015 practice of staying in sync 
with New York, which means that tzdb's predictions for its UTC offsets will 
become wrong in November 2018, and the abbreviations and tm_isdst flag will 
become wrong some time between March and November 2018 (although the article 
implies April, this could well be an error).

When the cabinet and/or the Turks & Caicos Weekly News get around to publishing 
the details of the decision, we should be able to update tzdb to reflect this 
change with some accuracy.
