Andrew Tridgell 2bc7d17e7a AP_NavEKF3: improved core comparison to check alignment 
this adds coreBetterScore() which takes account of tilt and yaw
alignment when comparing cores for lane switching

this ensures we don't switch to a lane that is unaligned due to the
zero error score for unaligned lanes

Harshit Kumar Sankhla edc3709653 AP_NavEKF3: implement sensor affinity using EK3_AFFINITY parameter 
this allows the EKF core index to be used to select a GPS/baro/mag
instance. This is an alternative to GPS blending that allows EKF lane
switching to be used to select the right combination of GPS and IMU
add logging to XKFS message

Harshit Kumar Sankhla d7edc946b6 AP_NavEKF3: Relative Error based Lane-Switching 
Improvments to the lane selection logic, we accumulate error for each
EKF lane relative to the primary for a more robust core selection
