The geometry was previously quad_deadcat in which front motors are closer to CG and thus more loaded in hover.
quad_wide is the same geometry as quad_deadcat except the CG is centered so all motors are loaded equally.
Flight logs on IRIS with deadcat mixer showed that
- all motors are equally loaded during hover (actuator_outputs 0 to 3 have similar values)
- a negative pitch offset is building up soon after takeoff (visible in actuator_controls)

- Missing get_sync() in verify function
- Allow some time to reboot before closing the serial port
  (closing the serial port drives TX low)

This is a temporary workaround for equal expressions in chip/sam_xdmac.c
and can be reverted once fixed properly in NuttX. Needed for the GCC 7
upgrade in #8551.

 - revert after #8689 is resolved

without this param set doesn't work -> adsp side never receives changes

If a log with multiple (dis)arming events was replayed, multiple logs were
created. This changes the replay to only create a single log.
