fix(simulator): miscellaneous cleanup fixes and improvements

[holahula]

Summary

Adds a few simulator improvements:

• simulator start now couples in building the root ironfish binary so the simulation running will always track ironfish changes
• removed util code that just wrapped client calls
• removed stop command because it was flaky
• made onLog / onError optional when executing CLI commands, default behaviour is now to log
• Added a tmp dir @ ~/.ironfish-simulator/simulations/{SIMULATION_RUN_ID} to store any simulation execution related files
• clean up formatting for verbose node logs by providing a tag filterer
  • todo (address later if this becomes a problem): add tag filtering support to log handlers added after node creation

Closes IFL-661
