Can plotting recipies for TH1D, TGraph, TGraphError be a part of the package?

Here is how I plot `TGraphError` extracted from `TFile`, ```julia f = TFile("test.root") c = f["myTGE"] # typo of object PyObject plot( vcat(c.xvalues...), vcat(c.yvalues...), xerr = vcat(c.xerrors...), yerr = vcat(c.yerrors...),...

I cannot read histograms from [this ROOT file](https://github.com/JuliaHEP/UpROOT.jl/files/6754057/histos.root.txt). I think it's a floating point arithmetic issue. ```julia julia> using UpROOT julia> UpROOT.TFile("histos.root")["h_comp_roi"] ERROR: Histogram edge vectors must be 1 longer...

Histograms: use `TH1::kIsAverage` to set `Histogram.isdensity`

...needs uproot4. See also https://github.com/scikit-hep/uproot3-methods/issues/99

We should think about implementing a custom `HEPHistogram` object with under/overflow bins *à la* ROOT.

Add support for `Base.close` to close files, etc.
