A newer build's list files hold records after their count that the game never reads

What to know

POD Gold's CIRCUITS.BIN says 32 and holds 35 rows; its VOITURE2.BIN says 8 and holds 23 records (measured). Gold's readers read the counted records only (observed: FUN_00471f24, FUN_00472020). The extra records name tracks and cars that are not on the disc ("Night", web cars): left over from the tools that wrote the files.

A reader that checks "file size = header + count × record" fails on such files; one that reads only the count cannot write the file back byte for byte. Read the count, read every whole record in the file, return the counted ones as the game sees them, and keep the rest for the writer.
