Manual context management example on readme has a bug

[aloktripathy]

The following code as listed on the readme page to manage context manually, has a bug.

import asyncio

from aiofile import async_open
from caio import linux_aio, thread_aio


async def main():
    linux_ctx = linux_aio.Context()
    threads_ctx = thread_aio.Context()

    async with async_open("/tmp/test.txt", "a", context=linux_ctx) as afp:
        await afp.write("Hello")

    async with async_open("/tmp/test.txt", "a", context=threads_ctx) as afp:
        print(await afp.read())


await main()
