Pythonic Mix-ins for ROOT classes (uproot3-methods)

uproot3-methods provides Pythonic mix-ins that extend the functionality of `uproot3` and `awkward0` arrays, adding common methods found in ROOT's C++ classes like TLorentzVector, TVector2, TVector3, and histogram types. It is specifically designed for the `uproot3` and `awkward0` ecosystems. The current version is 0.10.1 and it is primarily in maintenance mode, supporting the older `uproot3` branch.
