updated lateral, altitude and heading generic estimators so that repredictor can correctly use variable dt (requires using mrs_lib::varstepLKF)
calling setInputCoeff() in these estimators only when the new value is different from the old one (to prevent recreating repredictor models during each prediction)
lateral estimator - prevented setting of values outside the matrix dimensions, when creating matrix H for repredictor
