NFC Tag Data Reader with PyNFC

This function uses the PyNFC library to read data from NFC tags. It first connects to the first available NFC device, then scans for all available tags. If a supported MIFARE tag is found, it reads the data from the tag and returns it. If the tag type is not supported or no tags are found, it returns None.
