[BUG]: OffsetTracker::UpdateHistory can segfault in tests

Running pyfrc robot tests, I sometimes get these segfaults on Linux:

(gdb) bt
#0  0x00007ffff140ff10 in OffsetTracker::UpdateHistory(float) () from ~/.local/share/virtualenvs/rpy/lib/python3.10/site-packages/navx/_navx.cpython-310-x86_64-linux-gnu.so

An interesting note: I seem to only be able to reproduce the segfault with my team's code if I let the operator control and disabled tests run...

Start with the gdb backtrace for OffsetTracker::UpdateHistory(float) in the navx extension and trace the call path through AHRSInternal::SetAHRSPosData, SimIO::UpdatePeriodicFromSimVariables, and SimIO::Run. Reproduce the failure with pyfrc robot tests on Linux, especially with operator control enabled and tests disabled; done means the intermittent segfault no longer occurs.
