Subject: [PATCH] Fix dotvisualizer import error

firrtl-diagrammer library was removed from load-ivy.sc due to json4s
compatibility issues with Chisel 3.6. Thus, we shall remove obsolete
dotvisualizer import from cell-5.

Alternative visualization functions (visualize, visualizeHierarchy) are
implemented directly in source/load-ivy.sc and work without this import.

Closes #12
