(geography/R-sf) Updated 0.9.8 to 1.0.2

# version 1.0-2
* `st_read()` and `st_write()` using GDAL handle binary attributes
  (OFTBinary fields) ; #1721

* a `pivot_longer` method is added for `sf` objects (the `data.frame`
  method works, but raises a warning)

* `rbind.sf` preserves primary geometry column; #1717

* `configure` constrains using `--static` to `Darwin` platform; #1702,
  #1712, #1713

* old-style `crs` objects created with sf < 0.9-0 generate a message,
  and will cause a warning in the future.

* when `st_crs()` is called with a WKT2 as text input, its `input`
  field will be replaced with the CRS name (if it has one).

* GEOS (>= 3.9.0) operations use `GEOSGeom_setPrecision_r` to set
  precision of geometries; #1535

* `st_read()` with specified `query` ignores argument `layers`, and
  warns if it is given; #1444

# version 1.0-1
* fix regression in `st_intersection()`: when using s2 attributes were
  assigned wrongly; #1704

* `crs` (sf) to `CRS` (sp) conversion no longer needs validation by
  `rgdal`; https://github.com/edzer/sp/issues/107

* retrieve ESRI's WKT version of CRS by `st_crs(id)$WKT1_ESRI`; #1690

# version 1.0-0
* add `s2` to Imports:

* add Dewey Dunnington to contributors

* `sf_use_s2()` prints a message when using s2 has been switched to on or off.

* use `s2` spherical geometry as default when coordinates are ellipsoidal. This can
  be switched off (defaulting to planar geometry, using GEOS, as in sf < 1.0-0)
  by setting environment variable `_SF_USE_S2` to `false` before package `sf`
  is loaded, or by `sf_use_s2(FALSE)`; #1649

* `st_nearest_feature()` with missing `y` returns nearest features in
  the remaining set of `x`; https://github.com/r-spatial/s2/issues/111

* `st_write()` gains an argument `config_options` to set GDAL config
  options; #1618

* fix regression in `sf_project(..., keep = TRUE)`; #1635
