Typing for plotly_relayout event excludes autosize event

[rageycomma]

The typings for the relayout event omit the fact that an "autosize: true" event can be emitted by plotly.js. For instance, plotly's resize handler does the following:

plots.resize = function(gd) {
    gd = Lib.getGraphDiv(gd);

    return new Promise(function(resolve, reject) {
        if(!gd || Lib.isHidden(gd)) {
            reject(new Error('Resize must be passed a displayed plot div element.'));
        }

        if(gd._redrawTimer) clearTimeout(gd._redrawTimer);

        gd._redrawTimer = setTimeout(function() {
            // return if there is nothing to resize or is hidden
            if(!gd.layout || (gd.layout.width && gd.layout.height) || Lib.isHidden(gd)) {
                resolve(gd);
                return;
            }

            delete gd.layout.width;
            delete gd.layout.height;

            // autosizing doesn't count as a change that needs saving
            var oldchanged = gd.changed;

            // nor should it be included in the undo queue
            gd.autoplay = true;

            Registry.call('relayout', gd, {autosize: true}).then(function() {
                gd.changed = oldchanged;
                resolve(gd);
            });
        }, 100);
    });
};

This call passes {autosize: true} to the plotly_relayout event, however, the typings say:

onRelayout?: (event: Readonly<Plotly.PlotRelayoutEvent>) => void;

Which in plotly is:

export interface PlotRelayoutEvent {
	xaxis: PlotAxis;
	yaxis: PlotAxis;
	scene: PlotScene;
}

Hi, the plotly.js team does not actively maintain the typescript typings (more info in plotly/plotly.js#28)

I'd recommend opening an issue over at https://github.com/DefinitelyTyped/DefinitelyTyped

Thank you!
