Panpipelines

Changes in this release
* Provide option to perform shift in T1 space while calculating segmentation for chemical shift artefact
* Include pepolar fieldmap support in Basil pipeline for possible situations where MEGRE is missing but DWI-RPE exists.

Changes in this release
* Added support for slice to volume motion correction in eddy params
* Added support for chemical shift identification method that uses scalp surface.
* Increased granularity of echo-spacing definition to shared project level and provide option for retrieving echo-spacing from bids metadata
* Added shared project info to processing to relate subjects to original PAN projects

Changes in this release
* Add support for segmenting asl artefact (chemical shift) and excluding the artefact region from average ASL

Changes in this release
* Use bids filter to specify session and fieldmaps for fmriprep processing
* Add functionality to force bids download even if subject files exist on HPC. This will be necessary for processing fmriprep using dwei generated fieldmaps that will be generated on the XNAT

Changes in this release
* Specify session for asl processing and attempt to terminate processing if fieldmap not found
* Use bids filter to specify session for dwi processing
* Add support for subject exclusions. Prevent pipeline dependencies from affecting deployment if parent pipeline already run

Changes in this release
* This is a minor release. Just added logic to download TemplateFlow templates at the beginning of the pipeline run.
