[FEAT] Support OHLC Traces

[alexmerm]

Not sure If its possible or how much work it would be but it would be amazing to have support for OHLC plotly traces.

Hi @alexmerm,

I do not think that this is so much work, as there already exists an ad-hoc implementation in an issue (#284).

However, to implement this efficiently in a visualization tool agnostic manner in https://github.com/predict-idlab/tsdownsample, might take quite some time.

I will try to look into this issue somewhere later today, and provide a more clear timeline (and maybe a more optimized ad-hoc example) on how candlesticks-resampling can be integrated into plotly-resampler.

Kind regards,
Jonas
