Support for Draft 2020-12

[cakemanny]

Hi, would you be open to the idea of json-schema-diff supporting JSON Schema Draft 2020-12? i.e. accepting draft-07 compatible changes as pull requests?

The most interesting features for me would be the processing of definitions from $defs, the replacement for the definitions keyword and, though it's not unique to 2020-12, being able to resolve those definitions by their $id.

hello, i think it's within scope but we're not going to work on it.

Ok, cool! I'll hopefully try to open one or two small pull requests in the next couple of weeks.
