Support EEOC direct endpoint

[TacoTuesdayX365]

Currently the wrapper only supports EEOC to retrieve EEOC data based on a application id. Request to support direct end-point to list EEOC regardless of application id based on Greenhouse's documentation.

GET: List EEOC
GET: Retrieve EEOC Data for Application
