add support for rc522 rfid module

[maruf009sultan]

problem: it's not actually a problem but it would be better if you add support for rc522 rfid module which is from same manufacturer as pn532[as i know] but with less feature. In my region it's the only available module.

Solution: I think pn532 codes can be used for rc522, it would be better if you add support but not strictly nesessary.

alternatives: can use pn532

note: i'm not a native english pardon my language.
