IO
----
The IO module provides functions and classes for reading and writing files. Central access points are the `open` function for reading files, the `open_indexed` function for reading indexed files, and the `count_entries` function for counting entries in a file.

In addition, several `FileBuffer` classes are exposed, that can be used to specify how a file should be interpreted. Giving these as `buffer_type` argument to `open` overrides any automatic format detection based on filename suffix
