Fixes: libre-chip/grant-tracking#7

This adds a new SimOnly<T> HDL type and the corresponding SimOnlyValue<T> value, you can put just about any arbitrary type inside (it needs to support a few traits and [de]serialization to JSON) and the simulator will feed the values through the simulation, so you can have modules that have inputs and outputs that are BTreeMap<String, Vec<Option<u32>>> if you like.

See the test test_sim_only_connects for an example. Here's the generated .vcd file.
