bencode is supremely more efficient parser for torrents but
extremely strict in the format of the file. A custom parser based
on another implementation handles parsing that is more flexible
but it is not as efficient. Therefore when the file is well formed
bencode is used but if it fails then the custom parser is used.
If the custom parser fails then a ParsingError is raised.
