Request: add a title component/hovertext to the EasyButton

The EasyButton works perfectly, however it currently dus not allow for a hovertext. The EasyButton plugin that it is based on has a title component which adds this.

It is also not possible by adding a dl.Tooltip or dbc.Tooltip as a child or as a parent.

I don't know if it is hard to add, also it is not very important, but I'll add it as a feature request anyway.

Thanks in advance!

I think it should be fairly easy to add. I'll consider it next time I am coding.
