add react-svg-pan-zoom?

@yonicd I just remembered that texPreview uses svgPanZoom. Would it be helpful to add react-svg-pan-zoom as an additional viewer? I am updating the underlying js libraries and will submit to CRAN a new version soon.

that looks very nice.

yes that would be cool to have to pan zoom tikz outputs.

thanks!
