date-fns timezone utils
npm install @sourcefabric/date-fns-tzFork was created because original library couldn't be used with out webpack 4 setup.
1. There were issues with nullish coalescing, but that could have been solved by piping it through ts-loader.
2. Main issue was compilation of classes to ES5. It was not working when webpack was compiling it, but worked with babel here.
* Package name
* babel plugin added to compile classes to ES5
* babel plugin added to compile optional chaining to ES5
* version bumped to v1.2.1
