Incompatibility with React Native

[marc-wilson]

Also incompatible with Angular v 7.2.1

I immediately got 7 npm audit errors when I installed it (I had 0 originally)

Removed ical and got dependencies.
Added cross-fetch.

Published version 0.2.2.

I didn't test it on react-native or in browser. Hope it helped!
