bfconvert: PyramidOMETiffWriter failed to close with no flat and output pattern

[dgault]

Issue was raised on forum thread https://forum.image.sc/t/how-to-split-and-recombine-multiple-series-with-bfconvert/73662/2

In the thread the user had a multi resolution file (SCN format) with additional macro and label images and wanted only the image pyramid as an OME-TIFF. One of the attempts to achieve this was to use the noflat option with bfconvert and split the output into separate series using a pattern in the output as below:

bfconvert -noflat <original-file.scn> <output%%s.ome.tiff>

The conversion almost completed but threw an ArrayIndexOutOfBoundsException while closing the PyramidOMETiffWriter:
