In theory you don't iterate the records by counting bytes through
the file, but by using the file offsets in the headers.
For resources that 10 byte header you mention has the structure:
typedef struct {
UInt32 type;
UInt16 id;
LocalID localChunkID;
} RsrcEntryType;
where localChunkID = The local offset from the top of the PRC to
the start of the resource data for this entry.
By using the index you avoid issues to do with how many padding
bytes there are or what boundaries the records are on.
