Debug in devnet

[obycode]

With the way that the debugger is implemented, it should not be too difficult to enable a debug session on a live devnet. There are just packets being sent back and forth between VSCode and the debugger, which in simulated mode, is using stdin/stdout to transmit these packets, but in devnet-mode, this could easily be done over a TCP port instead. If this is implemented for devnet, then technically, there is nothing stopping you from debugging on a live mainnet node.
