feat(orchestrator): create orchestrator package

[tremarkley]

Closes #6

Creates the orchestrator package with the following properties:

• no config or arguments are read in and orchestrator spins up a default configuration of chains
  • fork mode support will be added in orchestrator: fork mode #25
• refactors supersim package to use orchestrator and moves all startup code for op-simulator and anvil into the orchestrator package

I'm wondering if we should consider adding a timeout at all https://pkg.go.dev/context#WithTimeout

[tremarkley]

@nitaliano I think for now we dont need one since this is only waiting on anvil instances to be ready, and that wait function already has a timeout in it:

supersim/anvil/anvil.go

Line 204 in e556e6e

timeoutCtx, cancel := context.WithTimeout(context.Background(), 10*time.Second)

. In the future it could be necessary if there are other services we need to wait on. I'll leave it out for now since we don't currently need it. Let me know if you think otherwise!

Good job! I'm starting to think you've been writing go longer than you're saying 😄
