Timeout exception when downloading large file

[Lqlsoftware]

Hi!
I am very interested in this project, and your code is so clean and readable to me. I would like to do something for this repo (or others XD).
There are some exceptions when using the script downloading files from channels:
When downloading large size of files, there is a great chance that some small-sized images will be downloaded together.
The await-sync programming model will stall other threads and coming to a timeout eventually, the last_message_id was not flush into the config.yaml before the timeout exception (damn...).
I'm trying to edit the script to prevent timeout exception when downloading a large file, and save the last_message_id when the exception occurs.
Do you have ideas to make the script better?

My bad. This issue is similar to #43. But it seems that I found the reason which causes the exception

@Lqlsoftware glad, you liked this project and found it useful. Thanks for getting into the details of the issue.
Yeah, in regards to the last_message_id if you are going to create a patch I would suggest changing the logic of the last_message_id to update in config.yaml for each batch of messages that are downloaded so even if the script is manually interrupted it would have the latest message_id.

We can also work on fixing the asyncio timeout issue by tinkering and changing how the coroutine & tasks are created currently - media_downloader.py#L175

Sure, I will pull a request for updating last_message_id in config.yaml later this day.
