no support for dict representation of plotly traces

[jvdd]

The following code works in plotly, but does not work when wrapping the constructor with FigureResampler.

trace = {
    "type": "scatter",
        #  "x": [1, 2, 3],
    "y": np.arange(5_000),
    "name": "some_trace",  # is not even required
}
fig = go.Figure()  # wrapping this will fail
fig.add_trace(trace)

We can support dict representation on 2 places;

1. in the constructor of AbstractFigureAggregator (-> not really sure if we want to do this)
2. in the add_trace method -> our type hinting indicates that we support dict input, but this is clearly not the case

should be fixed with #70, and will be released with plotly-resampler 0.7.0
