Depends on #210

Adds the story rows from Route 4 east of Mt. Moon to the Nugget, with the Cerulean-area maps.

• Maps (own commit): Cerulean's Mart and Gym, Route 25 and Bill's Sea Cottage, with clerk_front and misty_front.
• 00.14: Route 4's upper road only reaches Cerulean across water and routes never hop ledges, so the row walks to (93, 8), steps south down the ledge onto (93, 10), then routes to Cerulean's Center and heals.
• 00.15: up to (23, 7), one step onto the rival's middle trigger (23, 6), his battle (ends facing south, FAME CHECKER read with the battle text), back to the Center to heal.
• 00.16: onto Nugget Bridge, a step onto each trainer's row from the tile below (Cale, Ali, Timmy, Reli, Ethan, each beside the player), READY, then a step onto the Rocket's trigger (11, 15) for the Nugget and his battle; saves there facing east.
• Cerulean City gets its save card place (reader name and save_card_place).

Before the rival, 00.15 now buys 5 Potions at Cerulean's Mart (floor and budget 1500, since the money box can't be read yet), then GRINDs the lead to Lv22 on Route 4's grass east of Mt. Moon, from the patch (86, 16) pacing west, healing at Cerulean's Center. With Water Gun first, his Lv18 Bulbasaur took 6-7 Vine Whips' worth before fainting at any level a GRIND could reach; #120 now picks Bite against his party, and by my numbers Lv22 wins (about 70 HP of his damage against 61, which the Potions cover; about 100 at Lv18). From Lv17 that is roughly 50 wild battles.

Console checks: the ledge hop at (93, 9) landing on (93, 10) and the next route starting cleanly; the rival's scene ending on (23, 6) facing south with the overworld back; each bridge trainer's battle starting on the step onto their row; the Rocket's text, the Nugget and his battle, ending on (11, 15) facing east.

Testing: the PokemonFRLG::AutoStory, ::OverworldMaps, ::OverworldSim and other ::Overworld suites pass locally (163 cases), using an out-of-tree runner. New cases: the rival's and Rocket's triggers, the bridge trainer order, the run plan to 00.16, 00.15's Mart and GRIND before the rival (with the GRIND's nurse trip planned both ways), the Cerulean maps, and sim cases for Route 4 to Cerulean (including the hop), the Center to the bridge, and each bridge trainer.
