espa: some Spanish autopista exits renumbered by km (and other changes)

[neroute2]

ESP-CL AP1/ESP-PV AP1Arm:
1
2 -> 7
3 -> 36
4 -> 57
4A -> 66
5 -> 74
6 -> 78
A1 -> 84


ESP-AR AP2:
1 -> 19
1B -> 23
2 -> 43
3 -> 67
4 -> 114
ESP-CT AP2 is still sequential 5-12 (as of February 2025).

ESP-AN AP4 should take the left fork at exit 15. See signage at the split, km 14 on the left split, while the right split is AP-4A. In any case, 13 is not signed, so should be NIV on a new AP4A.

ESP-AN AP4 24 is only an onramp, so is unsigned and should be NIV_Pal.

Same for ESP-CL AP6 82; there's no offramp to be signed as exit 82, so change it to N110.

ESP-CT AP7/ESP-VC AP7Cas (still sequential):
12 -> 12A
C60 -> 12B
24 -> 23
AP2_W -> AP2
A7_N -> 298? AP7 takes the exit though
50 -> 302
51 -> 307
Or does AP7 end at A7_N -> A7? km posts south of there are for A7.

ESP-VC AP7:
527
532
535
58 -> 544
59 -> 558
60 -> 572
61 -> 588
61A -> 592
62 -> 608
63 still 63 as of February 2024, ditto for 64-66

ESP-VC AP7Tor 724 -> A7 (there's no exit, just a merge, so no signed exit number)
ESP-MC AP7 872 -> 878

ESP-AN AP7 (reverse direction):
Some numbers are unchanged; most overhead signs have a blank space but they are still on gore signs.
186 -> 1042
185 -> 1043
184 -> 1044
182 -> 1045
181 -> 1047A
180 -> 1047B
172
157 -> 1068
155 -> 1070
153 -> 1071
142
133

ESP-PV AP8:
Lap -> 4
Remove Oia? It doesn't look like you can legally U-turn at the rest area
70 -> 69
75 is gone, replaced by 77
AP8Bui -> 117
126 -> 125

ESP-GA AP9:
15 -> AP9Fer (no signed exit number)
65 -> 64
70 missing
81 seems to have no legal U-turn, and may not be signed as 81
130 is only an onramp, so has no exit number
177 -> A55 (there seems to be no signed exit number)

ESP-GA AP9Vig:
0V -> 151

ESP-NC AP15:
1 -> AP68 (no exit number signed)

ESP-AN AP46:
0 -> A45 (no exit, so no exit number)
missing exit 6
south end doesn't line up with point on A7

ESP-CL AP51:
81 -> AP6 (81 is only the number on AP6)

ESP-CL AP61:
61 -> AP6 (no exit, so no exit number)

ESP-RI AP68:
12 -> 12A
128 -> 12B
