developer_embryo: expose the sphere radius as a Radius parm

The internal sphere was hard-wired to radius 0.5. A new sphereradius
parm (labelled Radius, default 0.5) on the Main folder now drives radx,
rady and radz, so a full-size seed no longer needs a Transform after it.
Named sphereradius because the HDA already uses radius for Relax Radius.
