This ensures that any motion between construction and first update
will be ignored (this is usually the period between init and start
of an op mode). If teams want to track pose during that period,
they can call `updatePoseEstimate()` explicitly. This matches the
behavior of the 0.5.x localizers (without the annoying reset on
every pose estimate set).
The localizers also now log much more data to help troubleshoot
localization issues in the future.
