Release v0.0.20

Improved readability of --help. We now group arguments and generate comment/docstring-based helptext for nested dataclasses.

Release v0.0.19

Redesigned how annotations are parsed and used to instantiate fields; an iterative process is now recursive.

This is simpler, enables more informative error messages, and makes containers slightly more robust; supported annotations now include sequence types containing literals or enums (eg List[Literal[0, 1, 2, 3]] or Tuple[SomeEnum, SomeEnum, SomeEnum]).
