- mifare_classic_format_sector() now wants a sector instead of a block (the name was really disturbing);
- New public API functions for Block <=> Sector conversions.
- Allocate large blocks on Mifare Classic 4K in unit tests;
- Constraints sector number in mad_set_aid();
- Fix location of AID storage in mad_set_aid() (wrong variable name and offset, ECOPYPASTETOOFAST);
- New API function mad_sector_reserved();
- Use mad_sector_reserved() to avoid trying to use reserved sectors.
