fix: ignore warnings for duration in column summaries.

[kjgoodrick]

Binning duration columns is expected to fail and the fallback still produces the chart as expected. This change stops the warning from being emitted if the column type is a duration. I think a more robust fix would require support for durations/timedeltas in Vega-lite. For now the chart is good enough that emitting the warning is not helpful.
