Mathias Agopian 24f9bea8eb revert parts of dc5b63e40, which made gyro drift estimation unstable ... initialize the system covariance matrix with non-zero values for the gyro-bias part. this improves the initial bias estimation speed significantly. the initial covariance matrix should be small because the drift changes slowly. the real problem is that we're not starting with a good estimate of the drift, which this algorithm relies on. so with this revert, it'll take a while for the drift to be estimated but it won't be unstable.
