Update table

[drcandacemakedamoore]

I am unable to push to this repo. In order not to duplicate material in it, I therefore request that the table on scanner-to-computer.md be updated with a hyperlink tag (so I can link out to it) and slightly more information as follows:

Format Name	File Extension	Origin/Group	More info
DICOM	none or .dc	ACR/NEMA Consortium	https://www.dicomstandard.org/
Analyze	.img/.hdr	Analyze Software, Mayo Clinic	https://eeg.sourceforge.net/ANALYZE75.pdf
NIfTI	.nii (or .nii.gz)	Neuroimaging Informatics Technology Initiative	https://brainder.org/2012/09/23/the-nifti-file-format/
MINC	.mnc	Montreal Neurological Institute	https://www.mcgill.ca/bic/software/minc
NRRD	.nrrd		https://teem.sourceforge.net/nrrd/format.html
MGH	.mgz or .mgh (or .mgh.gz)	Massachusetts General Hospital	https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/MghFormat

Alternatively, I am sure with the right permissions I can push a PR @jhlegarreta
