ip_isr has many unit tests, but none tests IsrTask. I suggest adding such a task, likely using the data in obs_test
Add tests for ip_isr/isrTask
Set SUSPECT mask in ISR task and make saturation a double
A useful refactor to simplify testing isrTask.run(), would be to have the stuff inside the for amp in ccd: live in a do_amp() method. do_amp() can then be tested separately.
Closing as a duplicate of DM-15683
Marking invalid, as DM-15683 is subsuming this work (and that will eventually be marked "Done").
