Fixes of HypVINN & options for conform that disable critieria

[dkuegler]

• Some fixes to the HypVINN pipeline
  • formatting/doc
  • naming of HypoVINN->HypVINN (unified)
  • fix some errors with default hypvinn file names and arguments
  • generally improve and clean up the hypvinn interface and functions
• conform.py gets new flags --no_lia, --no_strict_lia, --no_img_size, --no_vox_size which deactivate parts of the conform script:
  • no_lia: rotation of the affine is not touched, image may remain RAS
  • no_strict_lia: rotation of the affine is adapted, but only towards LIA such that no interpolation would be necessary, but will also be LIA (never RAS)
  • no_img_size no padding/cropping of the image
  • no_iso_vox~no_vox_size~ no harmonization of voxel size, for example in combination with no_strict_lia, the image is not made iso. voxelsize
• Cleanup of shell scripts
  • Remove extra "2&>1" in shell scripts in echo statements (they never have stderr output)
