Add basic script to read tag using `pirc522` PyPI library

#!/usr/bin/env python3

from pirc522 import RFID

rdr = RFID(pin_irq=None)

# rdr.wait_for_tag()

(error, anticoll_uid) = rdr.anticoll()

uid = tuple(rdr.read_id())

anticoll_uid = (0x88,) + uid[0:3] + (0x8A,)

print("Card read UID: ", [hex(i) for i in uid])

print("Anticoll UID: ", [hex(i) for i in anticoll_uid])

print("Anticoll successful: ", not error)

r = rdr.select_tag(anticoll_uid)

print(r)

rdr.card_auth(rdr.auth_a, 10, [0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF], uid)

print("Reading block 10: " + str(rdr.read(10)))

# Always stop crypto1 when done working

rdr.stop_crypto()

# Calls GPIO cleanup

rdr.cleanup()
