First version to depend on awkward 0.9.0 and uproot-methods 0.5.0. Most of the motivation for a synchronized release was to manage a dependency between awkward and uproot-methods, and to introduce the first usable awkward-numba, but this synchronized release finally broke a dependency in which uproot's Pandas handler illegally used private methods from `awkward.JaggedArray`. Now all communication is at the level of public API.
