#473 disk not loads: 007 Trans-Master ...dsk
007 Trans-Master (1988)(ZX-Guaranteed)(Side A)[samdisk].dsk mentioned in [bugs:#450], uses a different track scheme than others:
The original format is 15x 256 byte sector in cylinder 36.
The 'faked' sector headers:
Side: 0, cylinder: 36 type: 0x00 tlen: 6250

This patch
- add a new "CPC_ISSUE_4" to detect this track layout in disk.c
- change MAX_SIZE_CODE to 6 (8192 byte) in upd_fdc.c
- fix the sector length handling in upd_fdc.c
