Relative imports and Type checker

[OGKevin]

I was getting some errors while running my local dev server. I've made a few changes so that I could run the dev server without errors.

• I've changed most imports to relative imports because of import errors.

•   __uri = f"https://sandbox.public.api.bunq.com/v{__version_api}"

  I was getting syntax errors from this line, by removing the leading f it got fixed.

• The privatekey property was not checking if the key was in bytes before continuing therefore this:

  if not isinstance(self.__privkey_pem, bytes):
        self.__privkey_pem = self.__privkey_pem.encode()
  print(type(self.__privkey_pem))

  The print can be removed tho.

• I couldn't test this yet but i thought it should be something like this, can confirm after the crypto issue is fixed which ill explain later.

  @property
  def api_key(self):
     #return None
     return self.__api_key
  

• Had to change privatekey to optional because I'll get an error from this line

The error that stops me from continuing my tests is the following:

line 1229, in _handle_key_loading_error
    raise ValueError("Could not deserialize key data.")
ValueError: Could not deserialize key data.

Im going to take break and go study will come back on this issue later.
