Fix IMU.h Missing Import

Fix IMUDataReporter Missing Import

Brief summary of changes

• When you consume this class you have to do the following shim to account for the missing import.

#include <OpenSim/Simulation/Model/Model.h> 
#include <OpenSim/Analyses/IMUDataReporter.h>

This adds the missing import to IMUDataReporter.h so you don't have to do this

Testing I've completed

Tested locally

Looking for feedback on...

Why add another header here in the header? typically we try to keep includes to a minimum and have clients of the class include all headers they need to consume it.

[alexbeattie42]

The correct place was actually in IMU.h. The model header is necessary since it is being directly used within IMU.h. Without this import the following compiler error is produced.

In member function ‘SimTK::Vec3 OpenSim::IMU::calcGyroscopeSignal(const SimTK::State&) const’:
~/opensim-core/sdk/include/OpenSim/Simulation/OpenSense/IMU.h:84:30: error: invalid use of incomplete type ‘const class OpenSim::Model’
   84 |         const auto& ground = model.getGround();
      |                              ^~~~~
