feat: remove change detection strategy from all components (#101)

BREAKING CHANGE:

For enhanced performance it is recommended that you add `changeDetection: ChangeDetectionStrategy.OnPush` on all components that use this library. This will restrict change detection to only run when the components inputs change

Closes #94
