Remove overlapping slots from AbstractKey subclasses
`PublicKey` and `PrivateKey` both define the `n` and `e` slots, which
are already present in their base class. This reduces the benefits of
having slots.
```shell
$ slotscheck -m rsa -v
ERROR: 'rsa.key:PrivateKey' defines overlapping slots.
- e (rsa.key:AbstractKey)
- n (rsa.key:AbstractKey)
ERROR: 'rsa.key:PublicKey' defines overlapping slots.
- e (rsa.key:AbstractKey)
- n (rsa.key:AbstractKey)
```
The Python docs say:
> If a class defines a slot also defined in a base class, the instance
> variable defined by the base class slot is inaccessible (except by
> retrieving its descriptor directly from the base class). This renders
> the meaning of the program undefined.
Python-RSA is a pure-Python RSA implementation. It supports encryption and decryption, signing and verifying signatures, and key generation according to PKCS#1 version 1.5. It can be used as a Python library as well as on the commandline. The code was mostly written by Sybren A. Stüvel.
Documentation can be found at the Python-RSA homepage. For all changes, check the changelog.
Download and install using:
pip install rsa
or download it from the Python Package Index.

Because of how Python internally stores numbers, it is very hard (if not impossible) to make a pure-Python program secure against timing attacks. This library is no exception, so use it with care. See https://securitypitfalls.wordpress.com/2018/08/03/constant-time-compare-in-python/ for more info.
