Ichthyostega a8231150a5 Library: need remapping of variadic sequence ...

This is a rather obnoxious limitation of C++ variadics:
the inability to properly match against a mixed sequence with variadics.
The argument pack must always be the last element, which precludes to match
the last or even the penultimate element (which we need here).

After some tinkering, I found a way to recast this as ''rebinding to a remoulded sequence'',
and could package a multitude of related tools into a single helper-template,
which works without any further library dependencies.

🠲 extract into a separate header (`variadic-rebind.hpp`) for ease of use.
