Make apx-chart inputs compatible with Angular strict templates

[lztetreault-dev]

New Pull Request

The inputs for apx-chart are optional in chart.component.ts, but are not properly marked as so. This causes issues for projects/libraries using Angular's strictTemplates.

Going from this: @Input() chart: ApexChart;

To this: @Input() chart?: ApexChart; (i.e. @Input() chart: ApexChart | undefined)

This makes it so that projects/libraries using strictTemplates will not complain about undefined values being passed into inputs when the component expects that can be the case.

All changes

• Update Angular minor version
• Fix spelling mistakes in the npm copyfile:license script.
• Make chart inputs compatible with Angular strictTempaltes.
• Add Zone.js to polyfills so that the demo can be run.
