Subject: [PATCH] constants: NETS_LIST to have deterministic ordering

Currently running the help command lists the supported chains in random order.
This patch changes the ordering to be lexicographical.

```
$ ./run_electrum --help
usage: run_electrum [-h] [--version] [-v VERBOSITY] [-D ELECTRUM_PATH] [-w WALLET_PATH] [-P]
