JsonSchemaRendere should handle nested data better

[Hades32]

Is your feature request related to a problem? Please describe.
Looking at large contracts in JF which are often deeply nested is very tiresome...

Describe the solution you'd like
Add a property to add indents and optionally collapsibility for nested objects. Also an additional vertical space between a nested object and a "normal" property would make it more readable.

Describe alternatives you've considered
Creating custom schemas for everything, but that's uneccessary work.
