Fixes #164. Currently, the PR only supports resetting on jumps back. Default behavior is the same as tf2_listener: Reset whenever ros::Time::now() is lower than the previous recorded one. Parameter ~time_jump_threshold can be used to specify that jumps smaller than the threshold do not result in resetting the filter (e.g. when running in real time and system clock jumps because of a time sync event). To disable the resetting behavior, set the threshold to DURATION_MAX.

I'm not sure if ABI compatibility is an issue for this package or not. If it is, the PR will need a few changes to retain ABI compatibility.

Beautiful, thank you! Breaking ABI should be okay for this package.
