Regenerate example files using new wkb writer

[paleolimbot]

As noted in #5! With the new WKB writer, we now always write ISO WKB whenever converting to geoarrow.wkb.

library(geoarrow)

tbl <- read_geoarrow_parquet(
  system.file("example_parquet/point_z-wkb.parquet", package = "geoarrow"),
  as_data_frame = FALSE
)

tbl2 <- read_geoarrow_parquet(
  system.file("example_parquet/point_z-wkb.parquet", package = "geoarrow"),
  handler = geos::geos_geometry_writer()
)

unclass(as.vector(tbl$geometry))[[1]]
#>  [1] 01 e9 03 00 00 00 00 00 00 00 00 3e 40 00 00 00 00 00 00 24 40 00 00 00 00
#> [26] 00 00 44 40
geos::geos_write_wkb(tbl2$geometry, flavor = "iso")[[1]]
#>  [1] 01 e9 03 00 00 00 00 00 00 00 00 3e 40 00 00 00 00 00 00 24 40 00 00 00 00
#> [26] 00 00 44 40
