consider removal of all longlat text

[mdsumner]

I'm toying with this in a branch, it seems PROJ 8.2.1 which is what rhub Ubuntu-asan uses has problems with user input "+proj=longlat*" or "OGC:CRS84". I've had to clean them out of vapour, and doing that here results in clean asan tests (not valgrind)

I don't yet know why PROJ on CRAN is not triggering similar "extra checks" problems as vapour is

Is this related to the below commented out test?

PROJ/tests/testthat/test-wk-trans.R

Lines 124 to 136 in 7c9f31f

	## we can't use proj=longlat or OGC:CRS84 with PROJ 8.2.1 and ubuntu-asan
	# test_that("proj_trans_create() adds crs type if needed", {
	# expect_no_error(proj_trans_create("+proj=longlat +datum=WGS84 +no_defs +type=crs", "+proj=longlat +datum=WGS84 +no_defs"))
	#
	# info <- proj_trans_info(
	# proj_trans_create(
	# "+proj=longlat +datum=WGS84 +no_defs +type=crs",
	# "+proj=longlat +datum=WGS84 +no_defs"
	# )
	# )
	#
	# expect_identical(info$source_crs, info$target_crs)
	# })

It may be related to creating a noop transform?
