Expose File::inner?

[trumank]

I'm using the high level API and would like the ability to dip down into the lower level structs without having to parse the file a second time using the low level API. Is there a way to do this?

There isn't a way to do this currently. #550 is one option I'm considering. The advantage it has over exposing File::inner is that it works for any T: Object, but I'm not sure yet if that is useful enough to worry about supporting.
