[dicom summary] Wrong field used for series number of files in the summary

[MaximeMulder]

The DICOM summary script writes the modality instead of the number of files of each series in the corresponding table column of the summary :

Example (using the ImagingUpload-18-41-C4ZlTl file of Raisinbread) :

...
<ACQUISITIONS>
Series (SN) | Name of series                  | Seq Name        | echoT ms | repT ms  | invT ms  | sth mm | PhEnc | NoF
1           | localizer                       | fl2d1           | 5        | 20       |          | 10     | COL   | MR
2           | t1_mpr_1mm_p2_pos50             | tfl3d1_ns       | 3.16     | 2400     | 1200     | 1      | ROW   | MR
3           | t2_spc_1mm_p2                   | spc3d1_278ns    | 497      | 3200     |          | 1      | ROW   | MR
...

This does not seem to affect other parts of the pipeline such as the insertion in the LORIS database.
