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.

235a8e07e3 Use a LRU cache for pip to wire map. 
This avoids storing the entire pip to wire map in memory with a moderate
runtime increase and a dramatic memory decrease (2 GB to 200 MB for
A50T).

3ae96bff88 Refactor GUI to use IdStringLists 
The GUI internally had an 'IdStringList' type that I hadn't spotted, to
avoid a conflict this is renamed to IdList which also reflects its new
purpose better.

6d23461bcd ecp5: Proof-of-concept using IdStringList for bel names 
This uses the new IdStringList API to store bel names for the ECP5. Note
that other arches and the GUI do not yet build with this
proof-of-concept patch.

getBelByName still uses the old implementation and could be more
efficiently implemented with further development.
