Incompatible with DynamicObj v. 3.0

Description

When installed with DynamicObj v. 3.0, Chart.Histogram crashes:

System.MissingMethodException: Method not found: 'Void DynamicObj.DynamicObj.CopyDynamicPropertiesTo(DynamicObj.DynamicObj)'.
   at Plotly.NET.GenericChart.ofTraceObject$cont@351(Trace trace, Unit unitVar)
   at Plotly.NET.GenericChart.ofTraceObject(Boolean useDefaults, Trace trace)

When downgrading DynamicObj to v. 2.0, it runs without issue. I haven't discovered if this affects other charts, or if it would work for histograms with different configuration options. I used the following options, though I cannot share the full code

Chart.Histogram(
    X = xValues,
    Name = modelName,
    MarkerColor = color,
    ShowLegend = showLegend,
    XBins = bins
)

Known workarounds

Just downgrade Dynamic Obj to >= 2.0 and < 3.0

Thanks for reporting this @ntwilson. We are aware of a few problems that the latest major version of DynamicObj brings when used with Plotly.NET (internal tests fail as well when upgrading the Plotly.NET repo from v2 to v3).

The best way is to just not upgrade this dependency for now. I think i will publish a patch to Plotly.NET that pins the version to > v3 though.

The core lib has been ported to use DynObj v4 (see #472), however it will take a while until this is live as it will be contained in Plotly.NET v6 which will include a few other large changes to the codebase.
