If value passed to the queue_declare arguments is int and greater then 128 then server reply that value was negative

How reproduce

Code:

import asyncio

import aiormq


async def test():
    connection = await aiormq.connect("amqp://guest:guest@localhost/")

    keys = {'x-max-length', 'x-message-ttl', 'x-max-length', 'x-max-length-bytes'}
    for k in keys:
        channel = await connection.channel()
        try:
            await channel.queue_declare('test', arguments={k: 129})
        except Exception as e:
            print(e)


asyncio.run(test())

Result:

PRECONDITION_FAILED - invalid arg 'x-max-length-bytes' for queue 'test' in vhost '/': {value_negative,-127}
PRECONDITION_FAILED - invalid arg 'x-message-ttl' for queue 'test' in vhost '/': {value_negative,-127}
PRECONDITION_FAILED - invalid arg 'x-max-length' for queue 'test' in vhost '/': {value_negative,-127}

Environment

OS: Ubuntu 19.10
Python: 3.7.5
Package version: aiormq==3.2.1

Similar bug in another library:
Polyconseil/aioamqp#204

I'm sorry but that is the wrong library to fix it. The bug actually here.

Yep, will report there if it's not fixed yet
