feat: cli overhaul with oclif

[arthurfiorette]

This PR adds a new cli under the name of tjsg. I kept the previous ts-json-schema-generator intact to keep compatibility with older versions and avoid another breaking release.

Also updated readme and set up oclif to automatically update some readme sections to keep up with cli changes.

New --flags were added and some unused ones were removed.

Some outputs:
