Relay SSL Support

Hello,

When I using the relay option:
```
$ hostyoself relay
[info]	2019/10/13 11:44:41 listening on :8010
[info]	2019/10/13 11:44:41 127.0.0.1:60028 GET /ws 2.406ms
[info]	2019/10/13 11:44:49 [::1]:60031 GET / 1.123ms
```
The localhost the connection does not appear to be using SSL (https); I can only connect via (http). Is there some trick getting it to work via SSL?

~ Thank you
