kfiv-decomp: matching decompilation of King's Field IV

kfiv-decomp reconstructs King's Field: The Ancient City's USA PlayStation 2 executable as matching C and assembly. Its build extracts a user-supplied disc, splits the executable with splat, and checks the linked ROM SHA-1; the author reports a byte-identical result while much game code remains assembly.
