After Siemens XA30 update, fmaps are misclassified as func and raise exceptions when run in heudiconv

[mjstarrett]

Our imaging facility recently updated the software for our Siemens Prisma 3T scanner to XA30. Prior to the update, I was able to run heudiconv using the reproin heuristic to convert and BIDS-ify my data (i.e., the protocol names for this study were compatible with reproin). However, while testing the same study after updating to XA30, I started getting an error on my fmaps, which use the PEpolar technique (i.e., fmap_dir-ap and fmap_dir-pa).

I did note that the ImageType in the dicom header has changed. Prior to the update it was...
['ORIGINAL', 'PRIMARY', 'M', 'ND', 'NORM', 'MOSAIC']
after the XA30 update it is now...
['ORIGINAL', 'PRIMARY', 'FMRI', 'NONE']

PROTOCOL NAMES:

• localizer
• anat-scout
• anat-T1w_acq-0.8mm
• func_run-01_task-rateDist
• fmap_dir-AP
• fmap_dir-PA

COMMAND RUN:
heudiconv -d sourcedata/{subject}/* -o . -f reproin -c dcm2niix -b --overwrite -s 1001

I don't have a solution, but I wanted to add that with the XA30 some of the tags used by reproin/heudiconv have been moved to the key ImageTypeText. E.g.,

"ImageType": [
    "ORIGINAL",
    "PRIMARY",
    "FMRI",
    "NONE"
  ],
  "ImageTypeText": [
    "ORIGINAL",
    "PRIMARY",
    "M",
    "MB",
    "TE3",
    "NORM",
    "DIS2D"
  ],
