Tumble detection is over sensitive

[krichardsson]

The tumble detection seems to be a bit too sensitive and sometimes triggers on a hard landing. This leads to the supervisor going into the locked state which requires a restart of the platform.

The tumble detection was updated in #1286

The values for upside-down detection is probably the problem

Better values might be something like

  const float acceptedUpsideDownAccZ = -0.5;  
  const uint32_t maxUpsideDownTime = M2T(60);
