Options to support splitting a rosbag file in duration and size chunks

[MCFurry]

Thanks for this nice service-based utility for rosbag recording!
We really like using this in our robots which are often in the field and should record important information in certain states.

We would really like to have a split option though to make sure the recorded rosbag file is never going to be too big. Some of our usecases are robots that drive around for hours and sometimes even days. It's a shame if they stop because of a full disk, so ideally we split the recorded rosbags and clean up older ones once the disk is almost full.

Hence this PR

I am also quite interested using these features.

@yoshito-okada, would it be possible to merge this and trigger a new bloom package version?

Thank you for the nice PR! It seems reasonable at first glance. I will take a closer look within the next week and then pull and release it.

For what it's worth: we've tested this branch for half a year already 🙂

Over a year now, still functional 😉
