Get data from charts upon mouse move and click

[gokulchittaranjan]

Description

The events currently supported in utils.py does not include mouse_move and click.
This is useful, for example, to get the OHLC data upon click, so that external action can be performed.

Code example

figures[idx].events.click += self.ui_on_graph_click

Should, for example, call the method self.ui_on_graph_click upon clicking the graph.

Method of implementation

Add relevant JS method to utils.py

Hi Louis, Thanks for the great package. I did get the latest version. It does not have the entire functionality that's in the PR - please feel free to reject it if it is not in line with your roadmap.

My use case is to get the OHLC data in addition to the price at a particular y-location.
