ALAR2 incompatible files

[priverop]

I found some alar2 files that cannot be exported using the tool.

Between the Alar2File there is always a gap of 34 bytes, but these files contain 36 byte gaps.

Our function to jump between Alar2Files is hardcoded, and it fails.

We should make it more robust. Although I think these are the only files that fails, so, don't worry about this too much.

Hexpat to help

u32 nameOffset = 0x10;

struct AlarFile {
    u32 fileID;
    u32 absolutePointer;
    u32 size;
    u32 unknown;
    u16 unknown2 @ absolutePointer - 2;
    u32 fileName @ nameOffset + 2; // this should return the first 4 bytes of the string // TODO: ToString
    u8 data[size] @ absolutePointer;
    nameOffset += size + 0x24;
};

struct ALAR2 {
    u32 magicID; // TODO: toString
    u8 version;
    u8 minorVersion;
    u16 fileNumber;
    u8 IDs[8];
    nameOffset += fileNumber * 0x10;
    AlarFile fileInfo[fileNumber];
};

ALAR2 alar @ 0x0;
