cors function

FutureOr Function(HyperioAzkadevHttpRequest, HyperioAzkadevHttpResponse) cors({ int age = 86400, String headers = '*', String methods = 'POST, GET, OPTIONS, PUT, PATCH, DELETE', String origin = '*', String crossOriginEmbedderPolicy = "credentialless", String crossOriginOpenerPolicy = "cross-origin", })

CORS Middlware.

Has some sensible defaults. You probably want to change the origin
