feat(app): add autoware module (ekf_localizer)

[nokosaaan]

Description

I added the ekf_localizer module.
I have ported the Autoware test case to Rust code.
Although there were multiple test cases for ekf_localizer, I believe that porting test_covariance.cpp alone is sufficient for dead reckoning in MRM. If it becomes necessary to add other test cases, I will consider implementing them as well.

@nokosaaan
The following five items appear to be missing. If this is intentional, please specify so in the comments; if they were simply overlooked, please implement them.

1. measurement_update_pose does not exist.
2. measurement_update_twist has been simplified.
3. vx_obs_var is fixed at 1.0, causing the logic that “does not trust velocity observations at low speeds” to be lost.
4. The delay compensation buffer is not functioning.
5. The initialization (initialize) does not account for TF transformations.
   Is it perhaps assuming that the input ros2bag is already transformed?

Are you implementing only “predictions for a single point in time + simplified velocity observation updates”?
