Fix PSX raw sector EDC/ECC generation

[DLPB2]

This fixes raw PSX CD-ROM sector integrity when IsoArchive writes or relocates sectors.

The issue was found while investigating myst6re/makoureactor#51. In current ff7tk, IsoArchiveIO::writeSector() constructs a 2352-byte sector with a zero-filled 280-byte footer, writeIso() can change the 2048-byte ISO payload without regenerating EDC/ECC, and copySectors(..., repair=true) reconstructs moved sectors from only their 2048-byte payload.

Changes:

• generate Mode 2 Form 1 EDC + P/Q ECC for sectors created by writeSector();
• generate Mode 2 Form 2 EDC (no P/Q ECC);
• repair only raw sectors whose payload is modified by writeIso();
• route Primary Volume Descriptor volume-size writes through writeIso();
• preserve the complete 2352-byte raw sector when relocating existing sectors;
• update destination MSF when a data sector is relocated;
• preserve existing Mode 2 XA integrity bytes when only MSF changes, since XA integrity is independent of the address;
• regenerate Mode 1 integrity when relocating Mode 1, because its address participates in integrity;
• leave untouched sectors byte-for-byte unchanged.

writeSector() remains limited to ff7tk's existing 24-byte Mode 2 XA header/subheader + 2048-byte payload layout. Existing Mode 1 sectors are handled by the relocation/repair helper rather than constructed through writeSector().

The EDC/ECC algorithm is the same implementation already tested through Makou Reactor on an FF7 PSX image.

Also do me a fave and add a credit for me :)

This needs to be fixed up as we don't do namespaces and the new file is not using Qt Object etc.. Ill get this looked over soon and updated so you guys can retest soon

Edit: since this is a collection of inlines ill leave it as namespace for now.. Added a commit to bump Qt t. 6.9.3 should fix the mac os build issue.
