TX: I-35 exit updates

[rickmastfan67]

There seems to be a completely random isolated on-ramp to I-35 SB between Exits 91 & 99 that has no other corresponding ramps for it.  It's been around since the beginning of GSV in '07.  Not sure how you'd want to go around labeling it.

missing -> 161

190A -> 190
190B -> 190A - Renumbered between Apr '22 & Nov '22 after the closure of '190A' SB between July '19 & Nov '21.

NEW -> 194 - Opened between Jan '22 & Jun '22.
NEW -> 197 - Opened between Mar '21 & Nov '21.
NEW -> 198 - Opened between July '19 & Jan '22.  Originally opened as 196 till becoming 198 in June '22.

239 -> 240A - renumbered between Apr '21 & Oct '21 both directions.
240 -> 240B - renumbered between Apr '21 & Oct '21 both directions.

missing -> 252A McNeil Rd

missing -> 259A (was original 259 NB offramp till they added a newer one much closer to the exit itself, see below)
259 -> 259B

NEW -> 270 - Opened between Oct '19 & Apr '21.
271 -> recenter. They've split traffic there onto 2 bridges now.

298 -> *298 or removed entirely.  Ramp became part of 299 between Nov '16 & May '18 after removal of the original 299 NB ramp.

NEW -> 309 - Opened sometime between Dec '18 & Apr '21.

318A -> *318A
318B -> 318 - area reconfigured with widening between Mar '14 & Oct '16

334B -> *334B - closed between Apr '22 & Sept '22 when new ramps for 335A opened and bypassed 8th St completely.
335A -> 335 (or remove)
335B -> 335A
335C -> 335B
336 -> *336 - closed between Oct '15 & May '18
^^ - This entire area (334-336) got reconfigured between Oct '15 & Sept '22.  US-77 will also need the adjustments.
