Newer json-schema versions support about circe-json-schema

[aelfric]

Along with this, the everit library that this project uses to understand JSON schema is end-of-life. The maintainers of that library recommend switching to json-skema instead. The only caveat is that the new library only supports the latest draft specification, and some schemas that were valid under everit might not be under json-skema. (We ran into this problem in another project that uses everit directly).

Would the project maintainers be open to a PR to switch the underlying library? This also relates to #8 issue.

Hello, I'm the maintainer of both the everit-org/json-schema and erosb/json-sKema libraries, I just found this project. I'd like to share a few thoughts:

• to use the everit library, you don't need the jitpack resolver anymore, it is now distributed on maven central with the com.github.erosb:everit-json-schema coordinates
• I understand that you need to support both draft-7 (and earlier) and 2020-12 versions. Maybe you could have 2 main versions of this library, 1.x staying on the everit library (hence draft-7) and 2.x migrated to erosb/json-sKema
• the json-sKema library offers better programmatic consumption of the validation, for example this kind of parsing can be avoided
