1. tcti/py: initial commit …

   Implmenet a TCTI module that will allow folks to write TCTIs in Python3.
   This will allow for more crazy and complex TCTI scenarios without having
   to re-write everyones stacks to use tpm2-pytss.
   
   Example Commandline:
   ```bash
   PYTHONPATH=$HOME tpm2_getcap --verbose --tcti=py:pytctitabrmd properties-fixed
   ```
   
   Example TCTI:
   For the ultimate in mind-bending: C -> Python -> C and back for
   efficiency :-p.
   
   ```python3
   from tpm2_pytss import TCTILdr
   from typing import Union
   
   class MyPyTCTI(object):
       def __init__(self, args: str):
           c = args.split(":", maxsplit=1)
           mod = c[0]
           args = c[1] if len(c) > 1 else "None"
           print(f"PYTHON: Initializing TCTI Ldr with mod: {mod} args: {args}")
           self._tcti = TCTILdr(mod, args)
   
       @Property
       def magic(self) -> Union[bytes, int]:
           # Optional Method
           print("PYTHON magic")
           return 42
   
       def receive(self, timeout: int) -> bytes:
           print("PYTHON receive")
           return self._tcti.receive(timeout=timeout)
   
       def transmit(self, data: bytes) -> None:
           print("PYTHON transmit")
           return self._tcti.receive(timeout=timeout)
   
   def tcti_init(args: str) -> MyPyTCTI:
       print(f"PYTHON tcti_init called with: {args}")
       return MyPyTCTI(args)
   
   ```
