Register an exception

The dApp should call this method when it cannot proceed with the request processing after an exception happens. This method should be the last method ever called by the dApp backend while processing a request.

When running in production mode, the Cartesi Server Manager pauses the Cartesi Machine and reverts the entire state of the machine to what it was before receiving the request. No HTTP status code will be sent or received.

When running in host mode, the Rollup HTTP Server returns the status code 200. In both cases, the input will be skipped with the reason EXCEPTION and the exception message will be forwarded.
