Improve security, myQ cloud password is visible, not encrypted or scrambled
* **Please explain your feature request in a one or two sentences.**
The myAQ plugin password is in plain text and visible in the config.json file or directly in the Homebridge configuration editor.
Wouldn't it be better if it was in base64 or some other kind of encryption instead of plain text, even in an encrypted file.


* **Is your feature request related to a problem? Please describe.**
Security flaw by having the password visible in plain text instead of an encrypted or scrambled format.


* **Any particular Meross devices that this relates to?**
No


* **Anything else?**
Example - Current
{
            "name": "Meross",
            "username": "yourmail@domain.com",
            "password": "HelloWorld1234",
            "connection": "default",
            "platform": "Meross"
        }

Example - hidden password in base64
{
            "name": "Meross",
            "username": "yourmail@domain.com",
            "password": "SGVsbG9Xb3JsZDEyMzQK",
            "connection": "default",
            "platform": "Meross"
        }
