Add full type annotations and black formatting across all modules

Browse source 
Annotated all functions with mypy --strict-compatible types (-> None, dict[str,
Any], Generator types, etc.), added # type: ignore for untyped third-party libs
(lxml), and reformatted with black. All 18 source files now pass mypy --strict
with zero errors.
