payroll-type — US:403b:Employee:Roth — needed separate since taxable

Since Roth contributions are taxable, there are some reports that
need to include these amounts in total salary (i.e., when running a
report that seeks to show total taxable income for an employee). As
such, we need a `payroll-type` specifically for Roth 403(b)
contributions.
