Add optional support for returning messages as JSON about sanic-dantic HOT 1 CLOSED

@rafmagns-skepa-dreag .

First of all, thanks for your affirmation and your suggestion.

I read your issue, but I'm not quite sure what you mean.

Did you mean to return the exception caught by ValidationError as a Json object?

In fact, for general request flow, it is correct to throw a parameter exception when it is detected.

However, as you said, some people may need all the abnormal parameters, and I will consider adding this function.

Recently, Sanic will release v21.3. And I am busy to checking the translation of sanic-guide to ensure that can be released simultaneously with Sanic v21.3.

Furthermore, sanic-dantic has not tested the compatibility of v21.3, and I am not sure whether it can be used normally on v21.3 now.

After the official release of Sanic v21.3, I will take some time to test the compatibility between sanic-dantic and Sanic v21.3

The next condition of sanic-dantic is support exception handling more friendly.

Thanks again for your suggestion！If you have any more ideas, please let me know !
