Support externalbrowser authentication #54
Description
For local development when using an identity provider such as Okta or SAML the official drivers support browser authentication: https://docs.snowflake.com/en/developer-guide/node-js/nodejs-driver-authenticate#label-nodejs-sso
The automated process works by spawning a local web server on localhost and opening the browser to a URL which authenticates with Snowflake and returns the login token back to the localhost page (and therefore back to the running application). But it can also operate in a simpler manner for headless usage, where the user has to manually copy the token from the webpage and provide it back to the running application.
It would be nice to be able to use that here as well.
