use Iterable[T] instead of Sequence[T] in Pool.map iterable

[fabridamicelli]

First off: Thank you very much for this package! :)

Here's a little thing about type hints I found. In essence the Sequece type is too restrictive. The function map can deal as is with any iterable.

Description

The type of the arg iterable should be a Iterable instead of Sequence. Here's pyright hint:

And here's after the fix

Here's an actually running example code:

import asyncio

from aiomultiprocess import Pool

async def f(i: int) -> int:
    await asyncio.sleep(0.1)
    return i

async def main():
    async with Pool() as p:
        vals_seq = [0, 1, 2]
        vals_iter = (i for i in range(3))

        print(await p.map(f, vals_seq))
        print(await p.map(f, vals_iter))

if __name__ == "__main__":
    asyncio.run(main())

which outputs:
