Have server indicate that Captcha is required

[dweeden]

Describe the solution you'd like

As I commented in question #320, the server seems to hang on start if eufy is wanting captcha unless one provide a -v verbose param.

It would be really helpful if the server logged that captcha is required at Info level in a manner similar to the way it does for 2FA (bold below). It took me quite awhile to figure this out and it would be nice to save others that time going forward.

Ideally, it would also emit the base64 data too with a suggestion to enter it into an online decoder such as https://www.base64decode.net/base64-image-decoder
