This is the first non-preview release of this library which supports Spark 2.0.0+.

This incorporates all of the changes from the v2.0.0-preview1 release, as well as the following bug fixes:

• Fix an issue where decimal-parsing logic was locale-sensitive, which could lead to incorrect results when reading decimals from Redshift when Spark was running in locales that use commas as decimal marks (#243 / #249).
