Updating hardcoded timezone lists in source code

[nartc]

As #10 #13 mentioned, there's a problem with guess property being set to true. Now, the problem is not the property itself but the "outdated" timezones list in the source code.

The library depends on moment-timezone for the "guess" functionality but probably not keeping up-to-date with moment-timezone in terms of what moment-timezone returns for its .guess() method. This leads to this line: this.countryChange.emit(this.allTimezones.find(x => x.zones.indexOf(this.currentTimezone) >= 0).iso); errors out as this.allTimezones.find(x => x.zones.indexOf(this.currentTimezone) >= 0).iso is undefined.

Is there any update/suggestion to this?
