Nano work server

This project is a dedicated work server for the Nano cryptocurrency.

It supports the work_generate, work_cancel, and work_validate commands from the Nano RPC. For details on these commands, see the Nano RPC documentation.

To see available command line options, run nano-work-server --help.

To use with the beta network (lower work difficulty), give the flag --beta. Working with both networks simultaneously is not supported.
