/*
From a list of parameters, create a genesis block / initial state
The process:
- Bootstrap state (MakeInitialStateTree)
- Create empty state
- Create system actor
- Make init actor
- Create accounts mappings
- Set NextID to MinerStart
- Setup Reward (1.4B fil)
- Setup Cron
- Create empty power actor
- Create empty market
- Create verified registry
- Setup burnt fund address
- Initialize account / msig balances
- Instantiate early vm with genesis syscalls
- Create miners
- Each:
- power.CreateMiner, set msg value to PowerBalance
- market.AddFunds with correct value
- market.PublishDeals for related sectors
- Set network power in the power actor to what we'll have after genesis creation
- Recreate reward actor state with the right power
- For each precommitted sector
- Get deal weight
- Calculate QA Power
- Remove fake power from the power actor
- Calculate pledge
- Precommit
- Confirm valid
