Pull Request description

• Replaces the aproximated calculation of total zso blocks with an exact calculation.
• Improved OoB checks in ZSO.
• Updated ZSO script should generate better images (tested with Prince of Persia - Sands of Time on internal HDD, it would hang with the older script, this one generates a working image).

@JoseAaronLopezGarcia, is it also possible to fix this issue? By the way, this issue is already fixed in ZISO compressor.

The ziso script allows changing a few parameters, they might help fix some games, specially the threshold paramenter.

There's nothing I can do about CDROM images since they have a different block size than DVD, what I do is use WinBin2Iso to convert the CD image to an ISO and then convert that to ZSO.

The ziso script enforces a block size of a multiple of 2048, we can get rid of this and have any arbitrary block size, though the zso reader in opl is optimized for 2048 and won't work for any other block size. It is possible to make a zso reader that would work with arbitrary block size (the original zso reader I made was based off one that did just that), but without a proper way to modularize OPL there's not much we can do.
