No mechanism to override codePointLimit in org.yaml.SnakeYaml.LoaderOptions

[AmateurECE]

Some OpenAPI documents, like the Redfish specification developed by DMTF, are larger than the default 3MiB limit set on input file size in org.yaml.SnakeYaml package. Users should have the opportunity to override this limit using the codePointLimit member in the org.yaml.SnakeYaml.LoaderOptions class, to avoid a YAMLException like the one below while running downstream code generation projects, like openapi-generator-cli.
