Daniel Agar 08f111f694 ekf2: consolidate airspeed fusion logic and helpers
- pass new airspeed sample around when available
 - can't completely eliminate _airspeed_sample_delayed until resetWind()
called from sideslip fusion is updated

Daniel Agar b4e845d7c0 ekf2: move controlDragFusion control.cpp -> drag_fusion.cpp 2023-02-22 09:08:33 -05:00
bresch 06ef39d05e ekf2: MC drag fusion - interpolate between X an Y "b" coefficients
Use the current sideslip angle to generate a drag coefficient that is a
mixture of X and Y coefficients, creating an elliptic distribution.

bresch 420f5ef2b7 ekf2: migrate drag fusion derivation to SymForce 2023-01-05 12:03:24 -05:00
bresch 04f76c932e ekf2: decompose drag vector into x-y components
The drag force is a vector.
drag_x = drag.norm() * vx / v.norm()

bresch 41abf695a8 ekf2: use more efficient covariance update computation
KSK' is faster to compute than KHP and is mathematically equivalent
