siotelegram 1.1.0

Sans io telegram api with couple io backends

# Sans io implementation of telegram api
Tiny telegram bot-api wrapper library.

## Reasons
* [aiotg](https://github.com/szastupov/aiotg) is framework, not library and have no proxy support.
* Raw api calls translation is better for understanding and will not break if telegram api will be changed.
* `snake_case`

## Features
* support both, sync and async ways to deal with io.
* Simple as telegram api is.
* `snake_case` api converted to telegram `camelCase`.
* Polling `offset` handled for you via `get_updates` method.
* Handling timeout between requests automatically (via `delay` keyword-only argument).
* Use any io backend you want.

## Implementation
[Sans io](http://sans-io.readthedocs.io/) implementation based on generators
for simplifying flow and holding state. `siotelegram` have io backends based on:
* requests
* aiohttp

## Installation
* sync: `python -m pip install siotelegram[requests]`
* async: `python -m pip install siotelegram[aiohttp]`

## Examples

### Common
``` python
import asyncio

import siotelegram


TOKEN = "token"


def requests_example():
api = siotelegram.RequestsTelegramApi(TOKEN, timeout=10)
response = api.get_updates()
print(response)


async def aiohttp_example():
async with siotelegram.AioHTTPTelegramApi(TOKEN, timeout=10) as api:
response = await api.get_updates()
print(response)


if __name__ == "__main__":
import time
# requests
requests_example()
time.sleep(1)
# aiohttp
loop = asyncio.get_event_loop()
loop.run_until_complete(aiohttp_example())
```

### Send files
``` python
import siotelegram
api = siotelegram.RequestsTelegramApi(TOKEN, timeout=10)
name = "capybara.jpg"
api.send_photo(chat_id=chat_id, caption="Hellow world!", files_=dict(photo=open(, "rb")))

# or from in-memory bytes
import pathlib
import io
data = pathlib.Path(name).read_bytes()
f = io.BytesIO(data)
f.name = name
api.send_photo(chat_id=chat_id, caption="Hellow world!", files_=dict(photo=f))
```
