Websocket over secure connection

If you want to run the websocket server over a secure connection, follow these steps:

1. create self signed certificates: https://letsencrypt.org/docs/certificates-for-localhost/#making-and-trusting-your-own-certificates

2. trust the self signed certs, eg on mac: https://tosbourn.com/getting-os-x-to-trust-self-signed-ssl-certificates/

3. pass the paths to the certificate and key using the --cert and --key CLI args, eg:

wspr --cert=./localhost.crt --key=./localhost.key

4. you should see the websocket is now running over wss:

WebSocket server started wss://localhost:3005
