Purely Functional, coroutine based algebraic effects in Python

# Example:

```python

from typing import Generator, Union, Any, Dict, Type

from ask import Ask, AskHandler

from files import ReadFile, ReadFileHandler

from console import Print, PrintHandler

from effect import run, Handler

def f() -> Generator[Union[Ask, ReadFile], Any, str]:

    name: str = yield Ask()

    content: str = yield ReadFile(name)

    return content

def test() -> Generator[Union[Ask, ReadFile, Print], Any, str]:

    content: str = yield from f()

    yield Print(content)

    return 'done'

handlers: Dict[Type, Handler] = {

    ReadFile : ReadFileHandler(),

    Ask      : AskHandler('effect.py'),

    Print    : PrintHandler()

}

run(test(), handlers)

```
