NTv1 grid shift: fix file offset for reading of shift values in ntv1_can.dat

2018-10-08T13:56:30+00:00

When investigating the format of NTv1 and comparing PROJ code with the actual
header of ntv1_can.dat, I discovered that the longitude & latitude shift values
started at offset 192, whereas PROJ assumed that the header was 176 bytes only.
This caused PROJ to use the wrong offsets values (shift of one grid sample by
longitude). So the effect was moderately visible, especially on the latitude,
but when comparing with NTv2, one can see that the longitude value after the
fix seems to closer to NTv2.

There was a mix of pj_log calls with and without a trailing newline.
pj_stderr_logger already adds a newline to the end of each msg, so
pj_log calls don't need their own.
