Bug Report

Issue:
Creating a histogram with any value that is equal to the max value will throw 'System.IndexOutOfRangeException', if there are more values than bins. This happens easily when using the overload that takes the binSize and not the bin count.

This is the offending code, taken from ScottPlot.Statistics.Common.Histogram

double[] hist = new double[binCount];

...

if (values[i] == max)
{
    hist[values.Length - 1] += 1;
    continue;
}

Even with only a few values this can get out of bounds easily, as long as the min and max properties reduce the binCount to less than the value count.

Reproducing:
Use the following code to easily reproduce the exception.

 var values = new double[] { 10, 20, 20, 10, 20, 10, 20, 10, 10, 20, 10, 10, 20, 15, 10, 30 };
 var (counts, binEdges) = ScottPlot.Statistics.Common.Histogram(values, 15, 30, 1, false);
