Given a Payslip ID, downloads the payslip file as raw bytes. Payslips are usually PDFs; the
Content-Type header gives the file's type.
The user the token acts for must have one role that can view payroll, open files and open payslip files,
even when your integration doesn't enforce role permissions; otherwise the request answers 403. A payslip of an
employee outside the data scope of every role that holds those permissions answers 404.
It is important to note that each country has a different payslip format and they are not authored by Remote.
