@peterbarker @tridge could you review this when you have a moment? It resolves the NaN pitch bug reported in mavlink/mavlink#2389 cc @DonLakeFlyer - A fix for your issue is ready for testing here. |

FP rounding in mavlink_quaternion_to_dcm can push dcm[2][0] outside [-1, 1], making asin return NaN. Mirrors the clamp in pymavlink/quaternion.py. Refs: mavlink/mavlink#2389

Closes mavlink/mavlink#2389.
asin(-dcm[2][0])returns NaN when FP rounding pushes the argument outside [-1, 1]. Clamps the argument in both v1.0 and v2.0 helpers, matching the existing clamp inpymavlink/quaternion.py.
