Raise exception on incompatible component data

[jeanconn]

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.
