shift_redcap_dates.py does not terminate if one of the spawned processed has error

[tashrifbillah]

It should because we added this block:

utility/shift_redcap_dates.py

Lines 121 to 130 in 5f1fd8b

	sigint_handler= signal.signal(signal.SIGINT, signal.SIG_IGN)
	pool= Pool(ncpu)
	signal.signal(signal.SIGINT, sigint_handler)
	try:
	pool.map_async(_shift_date, files, error_callback=RAISE)
	except KeyboardInterrupt:
	pool.terminate()
	else:
	pool.close()
	pool.join()

Way to reproduce

Just remove an entry from date_offset.csv that is in the beginning of date_offset.csv. Though we expect to see KeyError, it does not show anything. Rather it hangs indefinitely.

Interim solution

Make sure to run set_date_shifts.py so all entries are available in date_offset.csv.
