jpivarski added an interface to offload building of _some_ doubly jagged arrays to Awkward. This is the general plan for anything that `CanBeAwkward`, but for now, we just have this foot-in-the-door for one specific type. PR 96. (Only works when used with [awkward1 0.2.37](https://github.com/scikit-hep/awkward-1.0/releases/tag/0.2.37).) **TL;DR** this data type can now be read 80× faster.
jpivarski also added an interface for file-like objects (anything with a `read` and `seek` method).
