Perform auto authentication

This helper function lets you use environment variables to auto-authenticate on package load, intended for calling by gar_attach_auto_auth

gar_auto_auth(required_scopes, environment_var = "GAR_AUTH_FILE")

Arguments

required_scopes

required_scopes	Required scopes needed to authenticate - needs to match at least one
environment_var	Name of environment var that contains auth file path The authentication file can be a `.httr-oauth` file created via gar_auth or a Google service JSON file downloaded from the Google API credential console, with file extension `.json`. You can use this in your code to authenticate from a file location specified in file, but it is mainly intended to be called on package load via gar_attach_auto_auth. `environment_var` This is the name that will be called via Sys.getenv on library load. The environment variable will contain an absolute file path to the location of an authentication file.
