fpSup Unlocks OG4K CinemaDNG and Gyroflow on Original Sigma fp

A community project called fpSup has expanded the original Sigma fp to shoot open-gate 4K CinemaDNG at 3840x2560, plus four other CinemaDNG formats, lossless compression using the camera's own codec, Gyroflow gyro data output, a RAW monitoring view, and anamorphic de-squeeze preview. It runs via an AutoRun.txt file on the SD card, no firmware flash required, exploiting a factory debug shell built into Ver.5.02. Hard limit: original fp on Ver.5.02 only, not 5.02 or later, fp L not supported. All builds carry test, alpha, or beta labels.
