goshs route not protected, allows command execution

### Summary It seems that when running **goshs** without arguments it is possible for anyone to execute commands on the server. This was tested on version **1.0.4** of **goshs**. The command function was introduced in version **0.3.4**. ### Details It seems that the function ```dispatchReadPump``` does not checks the option cli ```-c```, thus allowing anyone to execute arbitrary command through the use of websockets. ### PoC Used **websocat** for the POC: ```bash echo -e '{"type": "command", "content": "id"}' |./websocat 'ws://192.168.1.11:8000/?ws' -t ``` ### Impact The vulnerability will only impacts goshs server on vulnerable versions.
