Hi ! Really nice (re-)work !

I made some comments in the review, let me know what you think.

Also, I was able to make it work using the following Python script :

In [1]: import pyHydrabus                                                                                         

In [2]: h = pyHydrabus.Hydrabus()                                                                                 

In [3]: h.write(b'\x0c') 
   ...: print(h.read(4))                                                                                          
b'NFC1'

In [4]: #Set ISO_14443A 
   ...: h.write(b'\x05')                                                                                          

In [5]: #Set RF on 
   ...: h.write(b'\x02')                                                                                          

In [6]: #Send REQA, get ATQA 
   ...: h.write(b'\x03\x26\x07') 
   ...: length = int.from_bytes(h.read(1), byteorder="little") 
   ...: print(f"{length:02d}  =>  {h.read(length)}")                                                              
02  =>  b'\x04\x00'

In [7]: #Send anticol, get ID 
   ...: h.write(b'\x04\x03\x00\x93\x20') 
   ...: length = int.from_bytes(h.read(1), byteorder="little") 
   ...: print(f"{length:02d}  =>  {h.read(length).hex()}")                                                        
05  =>  3fee983f76

I found an issue on the command numbers.
The BBIO_MODE_ID (0b00000001) was assigned to BBIO_NFC_RF_OFF. I reordered the command numbers in order to make the mode work like all the others.

This has been fixed in 9444937
