	/**
	 * Assumes that the ID field is a unique ID that never changes for staff.
	 * This must be true in order for duplicate staff to be avoided.
	 * Will automatically update staff data, including the site he/she is associated with.
	 *
	 * Expects the CSV string to contain comma delimited data in the form:
	 * ID, email, first name, last name
	 *
	 * The query in Aeries is: `LIST STF ID FN LN EM PSC`.
	 * A more complete Aeries query: `LIST STF ID FN LN EM BY FN IF PSC = 5`
	 * Note that you will want to run this query for each school, and the district.  The example above sets the school to #5 (PSC).
	 * Run the query in Aeries as a `Report`, select TXT, and upload here.
	 *
	 * Aeries adds a header per 'page' of data (I think 35 entries per page).
	 * Example:
	 * Anderson Valley Jr/Sr High School,6/11/2022
	 * 2021-2022,Page 1
	 * StuEmail,Student ID,First Name,Last Name,Grade,First Name Alias,Last Name Alias
	 * @type: Currently only supports 'CSV' or 'Aeries Text Report'
