VEP-014: product-type#spatial-profile

Hi all, 

I think this new product-type is fine. There is an equivalent dataproduct-type in EPNcore called "profile", with the following definition:

> Scalar or vectorial measurements along 1 spatial dimension, e.g., atmospheric profiles, atmospheric paths, sub-surface profiles, traverses...

Both terms are clearly equivalent.

I'd just update the description field as (adding "spatial"): 
> Description: An observable obtained along a one-dimensional spatial path.

>  Spatial profiles are commonly used in single-dish radio observations,
>  where a cross of about five beams centered on the target object is
>  scanned for computing flux backgrounds or pointing
>  corrections.  Other profiles used in radio astronomy scan over elevation

>  need discovery modes of their own because they have analysis modes
>  rather distinct from other data product types.  Whether the different
>  sorts of profiles need further separation remains to be seen in usage.
