Detailed Description

Reader with persistent in-file cache.

Example usage:
cached_reader = CachedReader(reader)
build_cache_step = cached_reader.build_cache('/tmp/cache.db')
with LocalSession() as session:

Every time new reader is created, it's expected that build_cache will be
called before setup_ex and usage of the reader. build_cache will check
existence of provided file path and in case it's missing will initialize it
by reading data from original reader. All consequent attempts to read will
ignore original reader (i.e. no additional data will be read from it).
