Keith Rothman c99fbde0eb Mark IdString and IdStringList single argument constructors explicit. 
Single argument constructors will silently convert to that type.  This
is typically not the right thing to do.  For example, the nexus and
ice40 arch_pybindings.h files were incorrectly parsing bel name strings,
etc.

D. Shah 75ee2fc4e6 Move RelPtr/RelSlice out of arches into common 
The bba approach seems widely used enough that it's reasonable for this
to become part of common code.

D. Shah e049d5f2fc nexus: Switch from RelPtr to RelSlice 
This replaces RelPtrs and a separate length field with a Rust-style
slice containing both a pointer and a length; with bounds checking
always enforced.

Thus iterating over these structures is both cleaner and safer.
