Emit error on invalid content

[Krakaw]

Please describe your changes

Adds an optional onError callback event and aborts rendering if the throwOnError Editor option is set to true.

How did you accomplish your changes

By adding an additional boolean to the EditorOptions and an error handler callback, we can toggle on emitting errors instead of silently handling them and not rendering any content.

This let's you set a an onError callback that gets called when invalid content is passed into the constructor or the setContent rawCommand.

How have you tested your changes

I've added emitError.spec.ts test file which checks that the onError event handler is not called when the throwOnError flag is false (the default behavior) and does get called only when invalid content is passed in.

How can we verify your changes

By creating an invalid json as the content and leaving the flag off, it will silently render nothing. Then set throwOnError: true and set the onError callback and it will be triggered with the error.
