Fix RuntimeError for the JSON export (#44)
* Fix RuntimeError for the JSON export

Re-enable mypy options (#43)
* Convert type comments to annotations

Notes:
- variable annotations are only possible for Python 3.6 and upwards

- class names as a result of a function have to be quoted
cf https://www.python.org/dev/peps/pep-0563/#enabling-the-future-behavior-in-python-3-7

This is ongoing work for #32

modified:   ssh-audit.py

* Do not use variable annotation

... as this feature works only for Python 3.6 and above only.

modified:   ssh-audit.py

* Re-enable strict_optional

`None` is a valid return type for mypy, even when you specify a certain
type. `strict_optional` makes sure that only the annotated return type
is actually returned.

modified:   tox.ini

* Re-enable `warn_unused_ignores`

Quote from mypy docs:
This flag will make mypy report an error whenever your code uses a
`# type: ignore` comment on a line that is not actually generating
 an error message.

modified:   tox.ini

* Re-enable `warn_return_any`

Quote from the documenation:
"This flag causes mypy to generate a warning when returning a value with
type Any from a function declared with a non-Any return type."

modified:   tox.ini

* Re-enable `warn_redundant_casts`

Quote from the documentation:
"This flag will make mypy report an error whenever your code uses an
unnecessary cast that can safely be removed."

modified:   tox.ini

* Remove `warn_incomplete_stub`

... as the documentation says
"This flag is mainly intended to be used by people who want contribute
to typeshed and would like a convenient way to find gaps and omissions."

modified:   tox.ini

* Re-enable `disallow_subclassing_any`

Quote from the documentation:
"This flag reports an error whenever a class subclasses a value of type
Any."

modified:   tox.ini

* Re-enable `follow_imports`

... and set it to `normal`.

For more information, see
https://mypy.readthedocs.io/en/latest/running_mypy.html#follow-imports

modified:   tox.ini

* Re-enable `ignore_missing_imports`

Quote from the documentation:
"This flag makes mypy ignore all missing imports. It is equivalent to
adding # type: ignore comments to all unresolved imports within your
codebase."

modified:   tox.ini

* Fix arguments for Kex initialization

`follows` has to be a boolean, but an int was provided.

This worked, as in Python boolean is a subtype of int.

modified:   ssh-audit.py

* Do not uncomment `check_untyped_defs` yet

modified:   tox.ini

* Change KexDH.__ed25519_pubkey's default type

It was initialized with 0 (int), and later it gets set with bytes.

Now, it gets initialized with None, and thus gets the type
Optional[bytes].

Optional means None or the named type.
