Subject: [PATCH] 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 their dialect copies.

Fixes #1065
