Class for working with RFID read/writer

[avida]

I have RFID reader / writer hardware. It works over SPI so implementation should be platform independent. Arduino already has some libraries who are doing that. This one seems to be most popular: https://github.com/miguelbalboa/rfid But it would fulfill my requirments. My one should work with stm32 as well and be a part of my code infrastructure. So do not fall into sin of copy-paste and create new genuine library. But you can borrow some ideas out there.
