This introduces a CallbackIterator object that can sit in the data
pipeline when setting image data and provide periodic callbacks to
allow recording status, checking for cancellation, etc. If the
callback raises an exception, that will bubble up to the read
operation and cause an abort.
The heartbeat is timer-based, but cooperative, which means if the
data pipeline stalls, we will stop heartbeating. The goal is to
provide a callback about once per minute, although blocking on
the pipeline could make that less regular of course.
