Roane County TN maintenance / bugfix update

ROANE COUNTY (not Los Injurus) bug-fix update for 0.19.x
I fixed a bunch of AI issues in Kingston in Roane County map here, they  shouldn't be so confused in-front of 'Worst Buy', or at the intersection  near Oldwell Wanker, or in-front of the school/water-front park.  It's  better anyways than it was.  I also enabled various AI routes near the  edge of the map again, as we're no longer as restricted with the max AI  node amount anymore in this 0.19.x game version.
I enabled road subdivisions on rural routes with very few nodes that  didn't have dedicated AI paths separate from the road texture itself.   This will help keep AI on track a little better.  I made sure  subdivisions were *NOT* used on bridges, over jumps, or other raised  road sections, due to it breaking raised (not flush with terrain) AI  paths if you use subdivisions on them.
I also fixed some grass growing through two bridges, in two spots near  Kingston.  One was on the highway overpass at the power plant access,  other was going over the river on the side route.
I deleted all the mesh road carving guides (those 'ribbons' under the  map).  I think I got them all, but there might be one or two somewhere I  missed.  I got most of them though.  Should help FPS a bit, but it's  still about 20% slower than I would like to see it.  I will do something  about this in the future - it's a draw call issue - which means it's  cpu bound, even on this 3700x and still with a 9900k.
I lowered the file download size / space on disk by 100mb by removing  some redundant things / proof textures (ones I use in the design stage).
I changed the cover art to match the SNES box style of my other  year-2020 map revisions (and changed the version number in text format)  to show that it now works with BeamNG 19.x.
 

Still some errata:
Poor performance - big map - is cpu limited
DO NOT ENTER sign texture does not work, is plain grey  -  Not worth  messing with as I'll be redoing the signs altogether in the future
Misc goofy AI bugs with weaving or not dealing with intersections  properly - it's an old map and the AI support is somewhat grand-fathered  in.
Various old-format texture normals - possibly slowing down the map rendering a bit.
AI will take jumps and crash badly or get stuck in Harriman downtown  area - this is not a bug & this is intentional as I made it that way  deliberately.  Use the jumps for car crashes and police chases.
The water might float vehicles with large tires - water default settings  have changed a few times over the last several game versions, I haven't  touched it since at-least when BeamNG 0.15.x was out.

The file size is 1.1gb.   Please enter the whole line below into your browser's url window (or on some browsers just highlight and right-click and choose 'open in new tab'), including the part after the # sign.  Let me know if you have any major issues with this map.

This will be on the repository tomorrow or shortly there-after, you won't need to download it twice.  Let me know if this doesn't function correctly on the Roane County TN discussion thread.
