Add plate motion model parameters to ITRF init-files.
Parameters for the plate motion models (PMM) for ITRF2008 and ITRF2014 are added to the ITRF2008/2014 init-files. The PMMs allow coordinates to be moved back and forward in time in plate fixed reference frames such as GR96 in Greenland which is defined as ITRF94@1996.623. Transforming an ITRF2014-coordinate to GR96 is done with: +proj=pipeline +step +init=ITRF2014:NOAM +t_epoch=1996.623 +t_obs=2017.584 +step +init=ITRF2014:ITRF94 +t_obs=1996.623 where the first step transforms the coordinate back in time to ITRF2014@1996.632 by using the ITRF2014 PMM. The second step transforms the ITRF2014 coordinate to ITRF94.
