RapidWright should track in the netlist if macros have been expanded or collapsed #388

When Vivado reads a netlist (EDIF file, for example) it will expand the macros in it before returning control to the user. RapidWright emulates this behavior by expanding upon read of a DCP and collapsing upon write of a DCP. However, if a DCP is written as an intermediate step, the netlist in memory stays collapsed and performing other netlist operations may fail afterwards (such as DesignTools.copyImplementation()). There should be a flag added to the netlist to track the current state of the macros so that these methods, or the user can query and expand the netlist appropriately.

What is the API to expand the macro?
