OpenAPI Schema to JSON Schema Converter

This Python library provides a utility to convert OpenAPI 3.0 Schema Objects into compatible JSON Schema Draft 4 representations. It addresses key discrepancies between the two specifications, such as `nullable` handling and removal of OpenAPI-specific keywords, to enable validation with standard JSON Schema validators. This package is a direct Python port of the JavaScript library `mikunn/openapi-schema-to-json-schema` (v2.1.0).
