Adding Typehinting or Stubfiles to mpyc

[Vizonex]

I was thinking about contributing to this library by adding some typehints since in python 3.10, you can use annotations so that tools like pyright or mypy can aid a developer in fixing and changing code in the longrun. I have a stubfile I wrote for the mpctools module as an example.

from typing import Callable, Sequence, Any
import operator
# unsure what runtime is but I'll figure it out...
runtime:  Any | None = None

class NoValueType(object):
    __doc__:str | None
    def __repr__(self) -> str: ...

_no_value: NoValueType

def reduce(f:Callable[[int, int], int], x:Sequence[int], initial=_no_value) -> int: ...
def accumulate(x:Sequence[int], f:Callable[[int, int], int] = operator.add, initial=_no_value) -> Iterator[int]: ...

Thanks for the suggestion. But I'd like to defer type hinting to a later stage. Note that there are already some results in this direction, e.g., see TNO-MPC/mpyc.stubs.
