fix(lods): remove incorrect BUN >= 7.50 renal point
Le Gall LODS awards renal +1 for BUN 17-27 mg/dL (then 28-55 -> 3, >=56 -> 5). The extra `bun_max >= 7.50 then 1` branch incorrectly scored BUN 7.5-16.9 as organ dysfunction. Remove it in MIMIC-III and MIMIC-IV sources and regenerate dialect copies. Fixes #1065
