Fix the EBOOT.PBP 'data is corrupted' boot failure on CFW by making the
converter match popstation byte-for-byte where it counts:
- build_toc: A0 entry byte 8 is the raw Red Book disc-type bitfield 0x20
(CD-ROM XA), not BCD(0x20)=0x32; A-point entries use control 0x41.
- extract_data_psp: copy only prx_size (u32 at DATA.PSP+0x2C), not the
whole zero-padded section.
- PSAR_ALIGNMENT: 0x50000 (matches popstation and the base PBP).
- SFO: patch the base PBP's PARAM.SFO in place (title + DISC_ID) instead
of rebuilding, preserving integer field types (0x0404) and values.
- Cue pregap: INDEX 00 pregap is already inside the bin file, so do not
re-emit zero sectors; only a PREGAP command adds external pregap.
Track starts/lead-out now match PSXPackager's merged-cue output.
