Add setters to encryption_algorithm & kdf_algorithm

[A6GibKm]

I was playing around the idea of changing the encryption algorithm in Password Safe (see https://gitlab.gnome.org/World/PasswordSafe/-/merge_requests/296) and I noticed that this was not possible doing db.encrpytion_algorithm = new_algorithm. Looking at pykeepass.py it seems that there are not setters for this property.
