Relay ol events to vue component for ol-interaction-transform

[deguich]

Is your feature request related to a problem? Please describe.
I need a ref to listen events

  const trans = interactionTransformRef.value.transform;
  trans.on("translateend", (e) => { console.log(e); });

Describe the solution you'd like

<ol-interaction-transform  @translateend="myHandler($event)"  />

This solution print a warning in browser devtools console :

[Vue warn]: Extraneous non-emits event listeners (translateend) were passed to component but could not be automatically inherited because component renders fragment or text root nodes. If the listener is intended to be a component custom event listener only, declare it using the "emits" option. 
  at <OlTransformInteraction  ... >

Mmm, I'm not sure to be expert enough for that.
I can try making PR ...
