on Zoom reset callback

[geekorlife]

Hi !
Thanks for this useful plugins !
I have the need to know when we click on the "Reset zoom" button but I don't see the possibility to pass a callback.
I maybe wrong, so let me know.

Workaround I'm using:

callbacks: {
  afterZoom() {
    let button = document.querySelector('.reset-zoom')
    if (!button.hasResetHandler) {
      button.hasResetHandler = true
      button.addEventListener('click', () => {
        // whatever
      })
    }
  }
}
