Unpack a data field that was packed using a complex packing algorithm as defined in the GRIB2 documention.

This subroutine Supports GRIB2 complex packing templates with or without spatial differences: It supports GRIB2 complex packing templates with or without spatial differences: Data Representation Tables 5.2 and 5.3).

Parameters

[in]	cpack	The packed data field (character*1 array).
[in]	len	Length of packed field cpack.
[in]	lensec	Length of section 7 (used for error checking).
[in]	idrsnum	Data Representation Template number 5.N. Must equal 2 or 3.
[in]	idrstmpl	The array of values for Data Representation Template 5.2 or 5.3.
[in]	ndpts	The number of data values to unpack.
[out]	fld	Contains the unpacked data values.
[out]	ier	Error return: 0 = No error. 1 = Problem - inconsistent group lengths of widths.
