 add script implementing the required tests.
 . 
 The RDNAP license requires the correct implementation of the grid
 corrections to be tested, as documented in the file:
 "Use of RDTRANS2008 and NAPTRANS2008.pdf"
 .
 There are 10 tests which need to be run in both directions,
 from ETRS89 to RD/NAP and vice versa.
 .
 The tests are defined in testrdtrans2008.json, and the test script
 testrdtrans2008.pl runs them for both directions.
 .
 Verbose output can be enabled by using the -v option, or setting the
 VERBOSE environment variable.
 .
 The points in tests 07 - 10 fall outside the grid, the output for
 these tests is not the expected floating point value, but a '*'.
 .
 These tests pass when the cs2cs output matches the overrides defined in
 testrdtrans2008.json.
 .
 Regarding tests 07 - 10, the "Use of RDTRANS2008 and NAPTRANS2008.pdf"
 file documents the following:
 .
   Points 07 - 10 are outside the region where interpolation between
   either the NLGEO2004 geoid or the RD correction grid points is
   possible. RD is defined only within the region enclosed by the
   following points (in RD), outside this region RD coordinates can
   be computed, but the output should be handled with care.
 .
   Corners of the validity region for RD:
   
     x (m)   y (m)
