As on import of EPSG, we remove the supersession of Canadian NTv1 file w.r.t NTv2
(because the default behaviour of PROJ is to ignore superseded operations). However
the NTv1 operation is advertized with an accuracy of 1m, whereas NTv2 is advertized
with 1.5m. Consequently on areas where both files are valid, and if both files are
available, NTv1 would be selected. So as a workaround, worsen the NTv1 accuracy to
2m so that NTv2 is used in priority.

Due to potential future shift to GTiff format, we don't want users of PROJ 6.3
being pointed to grids they won't be able to use.
So point to
- proj-datumgrid-1.8: already existing, unlikely to change before 6.3
- proj-datumgrid-north-america-1.3: to be released
- proj-datumgrid-europe-1.5: to be released
- proj-datumgrid-oceania-1.1: to be released
- proj-datumgrid-world-1.0: already existing, unlikely to change before 6.3

Relates to https://github.com/OSGeo/proj-datumgrid/pull/65 ,
https://github.com/OSGeo/proj-datumgrid/issues/22
As EPSG has no entry for it, we create a grid_transformation, as well as a
dedicated area of use based on the extent of the grid, under the PROJ authority.
With the hope to be able to remove it once EPSG has an entry...

Populated from realization_epoch column from EPSG
The 'publication_date' naming is from OGC Topic 2, and hasn't been yet adopted
by the EPSG dataset.

This was introduced in 63857c92b271bbcd10df0a032304982011acb2a9. Due to
the fix done in the previous commit, we can mostly revert the above commit.
We just keep the added tests and the custom WGS 84<-->WGS 84 (Gxxxx) null
transformations.

EPSG:9103 (NAD27 to ITRF2014 (1)) is now handled.
Note:EPSG:9104 (NAD27 to ITRF2014 (2)) is not currently, since it uses
for step EPSG:8861 (NAD83(HARN) to NAD83(FBN) (1))
an unsupported transformation method (NADCON5 (3D), EPSG:1075).

Note: a hack has been added into customizations.sql to cancel deprecatation
of USA geoid2012 grids by geoid2018 grids, as the later are not yet available
in proj-datumgrid-northamerica (https://github.com/OSGeo/proj-datumgrid/issues/55)

With limitation of https://github.com/OSGeo/PROJ/issues/1632 regarding
concatenated operations with more than 3 steps.
