TIGER 2023 support

[robe]

Looks like tiger 2023 is out and they changed their naming structure, so probably more work to do than past years

​https://www2.census.gov/geo/tiger/TIGER_RD18/LAYER/

I'm not exactly sure why the folder name is RD18 and why the change in files to be prefixed with tl_rd22 instead of just ​https://www2.census.gov/geo/tiger/TIGER2022/ (tl_)

But anyrate I suspect things have changed enough that I might not be able to backport this to 3.4.1, and just slate this for 3.5.0.

Okay this is not as much of a change as I feared. Seems changing loader_variables table is sufficient to make this work

UPDATE loader_variables tiger_year = 'rd22', website_root = 'https://www2.census.gov/geo/tiger/TIGER_RD18/LAYER';

is sufficient to make it work. That said I think I can backport this to 3.4.1 without issue.

I'm doing some tests on demo.postgis.net I have tiger_2022 loaded, now loading tiger_2023 with the changes to see if any issues before I push these.

So far so good. DC seems to have loaded fine and in middle of loading MA.

I guess Connecticut underwent some changes. We have one county less and 8 new Connecticut counties not in 2022 set.
