SampleColormapU32 always uses the current Style Colormap, instead of the cmap argument

I apologize I do not know how to refer to individual files or lines with markdown.
However the file is implot.cpp, near line 3403. The line with the fix is shown below, with the buggy line commented out and the fix right below.

ImU32  SampleColormapU32(float t, ImPlotColormap cmap) {
      ImPlotContext& gp = *GImPlot;
      cmap = cmap == IMPLOT_AUTO ? gp.Style.Colormap : cmap;
      IM_ASSERT_USER_ERROR(cmap >= 0 && cmap < gp.ColormapData.Count, "Invalid colormap index!");
      //    return gp.ColormapData.LerpTable(gp.Style.Colormap,t);
      return gp.ColormapData.LerpTable( cmap, t );
 }

Sorry about that. Just pushed a fix.
