Release 0.6.0

• Fixed and updated TypeScript definitions. #1132
  • Updated types to more accurately match the code implementation.
  • Added definitions for pre-built files (e.g. moment-timezone-with-data.js).

This release is a potential breaking change for TypeScript projects only.
The types are now more accurate, but consumers might hit errors if they were relying on the more relaxed types.

No implementation code has changed in this release.
