No check to see if the card is actually a mifare 1K/4K

[baconwaifu]

Using a mifare classic mini causes a segfault as the program is expecting a tag type of 0x8 or 0x18, not 0x9.

the main thread is not checking for get_trailer_block_for_sector() to return MIFARE_CLASSIC_INVALID_BLOCK and segfaults.

A solution would be a simple sanity check:

if (block == 0xFFFFFFFF) {
    printf("The card is not a Mifare Classic card");
    return 1;
}

is there any workaround to use mfuck with Mifare Classic mini ? regards
