Raise exception on incompatible component data

This came up in the context of the PSMC checker, as Dick updated the tool to feed in the detector housing heater state with:

```
model.comp['dh_heater'].set_data(dh_heater,dh_heater_times)
```

but dh_heater was a numpy array with integer type not a boolean array.    It would be great if the model components could verify data type and raise an exception as needed.
