Proof of work consensus for Substrate.

To use this engine, you can need to have a struct that implements PowAlgorithm. After that, pass an instance of the struct, along with other necessary client references to import_queue to setup the queue. Use the start_mine function for basic CPU mining.

The auxiliary storage for PoW engine only stores the total difficulty. For other storage requirements for particular PoW algorithm (such as the actual difficulty for each particular blocks), you can take a client reference in your PowAlgorithm implementation, and use a separate prefix for the auxiliary storage. It is also possible to just use the runtime as the storage, but it is not recommended as it won't work well with light clients.
