Go HEP release 0.37.0

Release v0.37.0 is out of the oven.

This release contains one major API breakage : we’ve dropped support for Gio (following suit of gonum/plot), and thus removed pawgo and hplot/cmd/iplot. We may reintroduce pawgo and iplot some time in the future, perhaps based off modernc.org/tk9.0.

Go-HEP v0.37.0 is the last release to be cooked with GitHub. Go HEP is indeed migrating to codeberg.org/go-hep.

hplot

• hplot/cmd/iplot: command removed, following removal of Gio support
• add PreSteps, MidSteps and PostSteps options for drawing steps with a S2D plotter

fit

• add Poly to fit polynomials
• add Func1D.Hessian to (numerically) compute the Hessian matrix at a given point in the parameter space

groot

• added support for ROOT 6.34/04
