Overlapping Chunks in generated rosbag #19

I noticed that I get an error when I try to play the .bag file generated using /rosbag_snapshot on Webviz.

Here is the error message-
This bag has many overlapping chunks, which means that we have to decompress many chunks in order to load a particular time range. This is slow. Ideally, fix this where you're generating your bags, by sorting the messages by receive time, e.g. using a script like this: https://gist.github.com/janpaul123/deaa92338d5e8309ef7aa7a55d625152

Is there a way we can fix this issue without having to reorder the bag file later?

Thank you.
