Fix and refactor GPS L1 C/A KF tracking dump reader and plotter.

The KF tracking dump reader now follows the parameters dumped by kf_tracking.cc

lib/gps_l1_ca_kf_read_tracking_dump.py:
- Rewrite using the same _RECORD_FORMAT / _FIELD_NAMES architecture as
  dll_pll_veml_read_tracking_dump.py: one struct.unpack per record and
  EOF handling, dropping the v1..v22 / bytes_shift / seek.

gps_l1_ca_kf_plot_sample.py:
- map innovation -> carr_error; drop r_noise_cov

lib/plotKalman.py, lib/plotTracking.py:
- Skip the "Estimated Noise Variance" panel when r_noise_cov is absent.
- Replace fig.canvas.set_window_title() with
  fig.canvas.manager.set_window_title(). The canvas method was deprecated
  in matplotlib 3.4 and is gone in current matplotlib (3.6.3 here), where
  it raised AttributeError. Ref: https://github.com/raysect/source/issues/383
