Occasional panic in ahrs_simple.go

Under some situations it apparently possible that ``func MakeUnitVector(vec [3]float64) (res *[3]float64, err error) {}returns an error. see : https://github.com/b3nn0/goflying/blob/master/ahrs/ahrs_defs.go#L148 This condition is not checkedahrs_simple.go`

rotmat, err := MakeHardSoftRotationMatrix(*ha, [3]float64{1, 0, 0}, *he, *se)

Unfortunately I did not have time to dive deeper into it yet to understand what the exact condition is..
