mc4.sav: reconstructing the Midnight Club: Los Angeles save format

mc4.sav documents the save format written by the Midnight Club: Los Angeles recompiled PC runtime. It maps big-endian section records, career values, garage slots and performance-upgrade bytes from observed saves, and supplies a browser editor and PowerShell commands for inspecting and changing supported fields.
