add SAIP template handling + v3.1 definitions

Browse Source 
This adds classes for describing profile templates as well
as derived classes defining the profile templates of the
"Profile Interoperability Technical Specification", specifically
it's "ANNEX A (Normative): File Structure Templates Definition"

We need a machine-readable definition of those templates, so
we can fully interpret an unprotected profile package (UPP),
as the UPP usually only contains the increment/difference to
a given teplate.
