Curio Integration (PDP)

# Summary

Integrating Forest with miner software is a bit tricky, mostly due to very high hardware requirements for even a testnet.

The twist is that we can offer only PDP integration capabilities. While Forest + Curio mining was always a rather idealistic dream with little economical incentives (the mining rig cost eclipse any Lotus costs), Curio (PDP-only) can actually run on a commodity hardware. So now if you'd be a PDP provider, your setup cost wouldn't go down by sub-one percent but probably closer to 50%+ by having Curio + Forest.

# Risks & Dependencies

The integration might not work out of the box; most RPC methods _should_ be implemented, but we won't know until checked. There might be also some assumptions on Curio side that the node is actually Lotus; to be investigated.
