Attempt to load an Access Token using Google Credentials.

1. First check to see if the environment variable HELIOS_GOOGLE_CREDENTIALS is set and points to a readable file
2. Otherwise check if Google Application Default Credentials can be loaded

Note that we use a special environment variable of our own in addition to any environment variable that the ADC loading uses (GOOGLE_APPLICATION_CREDENTIALS) in case there is a need for the user to use the latter env var for some other purpose.

Returns:

Return an AccessToken or null

Throws:

IOException
