fix Singleton inheritance
- Fix the previous behavior of Singleton, when the same instance is
returned for each possible subclass. Now one instance for each subclass.
- Add an explanation about possible changes to the value of the
`__init__` argument.
- Remove `from __future__ import annotations` because of Python3.7+
requirements declared in `README`.
- Fix according to PEP-8 (80 symbols).1 parent 14eacc5 commit 308cf47
