Brett Smith aa488effb0 books.Loader: New loading strategy based on load_file. RT#11034.
Building a string and loading it means Beancount can never cache any
load. It only caches top-level file loads because options in the
top-level file can change the semantics of included entries.

Instead use load_file as much as possible, and filter entries as
needed.
