Legend plugin is missing events property in typings

[elinake]

Expected behavior

I have a custom plugin that listens to mouseup events, and I want to be able to use the signal disabling feature of legend. Usually plugins take use of events property, but with typescript that is not possible, because it gives error that events property doesn't exist (see example).

Without typescript it is possible, but not using typescript is unfortunately not an option for me.

Current behavior

What happens now in the example, is that legend's onClick is run twice, therefore disabling and enabling the signal immediately. In the code it looks like mouseup and onClick are treated as the same event:

582:

function isListened(type, opts) {
  if (opts.onClick && (type === 'click' || type === 'mouseup')) {
    return true;
  }
  return false;
}

528:

  handleEvent(e) {
    if (!isListened(e.type, opts)) {
      return;
    }
    if (e.type === 'mousemove' || e.type === 'mouseout') {
    [...]
    } else if (hoveredItem) {
      call(opts.onClick, [e, hoveredItem, this], this);
    }
  }

The fix doesn't work, because Legend does not extend Plugin.
