Description

There are attributes for min/max and regular expressions, maybe more. I'm not sure they're checked by Json.NET when deserializing, but it would nice to have them in general. Also, the JSON Schema generator of Json.NET will use them to reproduce the constraints in the schema.

Contributor guide

Research direction
Examine the existing quicktype code for C# output and add support for generating DataAnnotation attributes based on JSON Schema constraints. Look at how min/max and regex are handled in the schema and map them to attributes like Range and RegularExpression. Verify by testing with Json.NET schema generation.
