Connect coal master node to identitynode internally
...
Instead of exposing master node to downstream, wrap everything inside
the IdentityNode with N+1:N+1 edges. The inward edges exposed to the
upstream nodes are only N edges. Needs more testing.

Set lgSize=0 as memtrace addresses are not aligned
...
This is TODO, we need to have a logic inside MemTraceDriver that aligns
these addresses to word boundaries and sets the right masks, similar to
how an actual core issues load/stores.

Maintain cycle inside Verilog instead of C
...
The Verilog wrapper maintains the cycle state, and C parser becomes a
combinational logic which Verilog queries to check if there is a request
