Fix TS options definition to include unwindArrays, useLocaleFormat

As was pointed out in #158, the unwindArrays option was missing from the TypeScript definitions. After further investigation, it was also found that useLocaleFormat was missing. Both options were added to the TypeScript options definitions in this commit.

Fixes #158
