[Feature Request] Support --format=json option for querly test

[ybiquitous]

Hello,

I want to parse the output of the querly test command more easily and safely.
So, what do you think about the suggestion to add a new option --format=json to the querly test command?

The option is almost similar to the querly check command. Here is the current querly check usage:

$ querly help check
Usage:
  querly check [paths]

Options:
  [--config=CONFIG]  
                     # Default: querly.yml
  [--root=ROOT]      
  [--format=FORMAT]  
                     # Default: text
                     # Possible values: text, json
  [--rule=RULE]      
  [--threads=N]      
                     # Default: 8

Check paths based on configuration

On the other hand, the new options of querly test will be similar:

• querly test (without --format, defaults to --format=text. The output is the current one)
• querly test --format=text
• querly test --format=json

I would be happy if you could consider this suggestion.
Thank you.
