AppSync Schema Converter

This project is a Fork from gitlab.com/vicary/appsync-schema-converter and include the following list of modifications:

• Added support for cognito_groups inside both @aws_auth and @aws_cognito_user_pools directives.
• Added support for INPUT_FIELD_DEFINITION directives.
• Various upgrades (docs, dependencies, formatting, ...).

The sole purpose of this package is to convert modern GraphQL schemas into AppSync compatible version.

1. printSchema() is a copy of graphql@^14.4.2/utilities/schemaPrinter.js@printSchema with includesDirectives: Boolean option added.
2. convertSchemas(schemas: [string]) takes an array of GraphQL SDL string and converts them into one single AppSync comptaible schema.
