suitcase.tiff_series and suitcase.tiff_stack do not export tiff images

[st3107]

I was trying to use suitcase.tiff_series to export the tiff images of diffraction data in the workstation xf28id1-ws6.

from databroker import catalog
import suitcase.tiff_stack
import suitcase.tiff_series
db = catalog['xpd']
run = db['e2b7d9c5-38a9-4787-9cae-4d7e18d02697']
docs = run.canonical(fill="yes")
suitcase.tiff_stack.export(docs, '.')
suitcase.tiff_series.export(docs, '.')

No tiff files were generated. I also tried other run, the result was the same. I could make sure that there is a diffraction image with key "pe1_image" in the "data".

These "suitcases" infer whether or not they should export a given column (a.k.a. "field") based on its dimensionality.

suitcase-tiff/suitcase/tiff_stack/__init__.py

Lines 272 to 280 in 935765f

	for field in doc['data']:
	for img in doc['data'][field]:
	# Check that the data is 2D or 3D; if not ignore it.
	data_key = descriptor['data_keys'][field]
	ndim = len(data_key['shape'] or [])
	if data_key['dtype'] == 'array' and 1 < ndim < 4:
	# there is data to be written so
	# create a file for this stream and field
	# if one does not exist yet

If you are running this locally, would it be possible to add some prints to investigate what dimensionality it is seeing here? We should add some logging to make it convenient to investigate in the future.
