Ignore medial wall, via creating a cortex-only submesh.
The submesh is based on the subject/label/?h.sortex.label file
a vertex mapping between meshes is saved, and used later to map the per-vertex data for the submesh back to the full mesh
running this requires a cortex-label file that is down-scaled to the mesh resolution (e.g., ico6). a script to dwon-sample labels is included.
the important functions (vertex submesh, data re-mapping) are implemented in libfs in a general-purpose fashion, and this PR uses the latest libfs version with these features.
