Constructor for periodic_spline
Populates a periodic_spline instance spl representing the
periodic data y(x) of length n and periodic on period. Note
that the spline library expects period > x(n) - x(1), which
means the input data shouldn't include the duplicate periodic
point. As a convenience the user can pass data with the
duplicate point and set drop_last_point = .true. to
automatically exclude the duplicate point.
