Missing error callback

[agnlez]

Issue: The layer manager doesn't provide a way to handle internal errors and callback them to the host application. If an error comes up, it will trigger and that's all. The host app cannot do anything about it.

Proposal: creating an error callback to manage any error triggered by the layer manager. This error callback would be optional.

// error could be an error object (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error) and we would standardize the way of triggering errors
<LayerManager 
  // props
  onError={(error) => { // do something with error object }}
/>
