Looks very good to me! If you'd find a way to make the code easier to understand I'd welcome that, but that's optional
Previously, when a user asked to interpolate a value close to the edges of the histogram, the function would generate an error. This is inconsistent with the TH1 version of Interpolate. Here, the valid range is extended by assuming that the histogram is constant at its edges (i.e. the imaginary next bin outside the axis limits has the same bin content as the last bin inside the limits, like in TH1). From here, the trilinear interpolation proceeds as before. Fix root-project#10678

When a user asks to interpolate a value close to the edges of an axis,
the function would generate an error. This is inconsistent with the TH1
version of Interpolate.
Here, the valid range is extended by assuming that the histogram is
constant at the axis limit (i.e. the imaginary next bin outside the axis
limits has the same bin content as the last bin inside the limits). From
here, the trilinear interpolation proceeds as usual.
