callback function on new API

[lekoOwO]

I'm using the latest commit in master branch.

Before this update, I used to do:

ChatReplayDownloader().get_youtube_messages(video_id, callback=my_callback)

But now I don't see a callback parameter provided, is there any fix? Thanks!

Hi there! The new version now uses generators to manage chat objects :) This makes it a lot easier to define better/more complex callback options. As an example:

from chat_replay_downloader import ChatDownloader
video_id = 'J2umj9SgdFU'  
chat = ChatDownloader().get_chat(video_id) # creates a generator
for message in chat: # you can now iterate over it!
    print(message) # callback goes here

would continue outputting:

{'action_type': 'add_chat_item', 'message': 'finally Vishy with new camera angle', 'message_id': 'CkUKGkNQX2cyLS1QeHU0Q0ZmSU1mUW9kVTMwTDRBEidDSi1ScWRLUHh1NENGZXFEckFJZF9pUUhZUTE2MTIwOTQ0NjQ0ODY%3D', 'timestamp': 1612094465568923, 'author': {'name': 'Samir Ghimire', 'images': [{'url': 'https://yt3.ggpht.com/ytc/AAUvwni2C4pmWWWjaxY2ZUnFjYqiyCpD3Y-mXhozkw=s32-c-k-c0xffffffff-no-rj-mo', 'width': 32, 'height': 32, 'id': '32x32'}, {'url': 'https://yt3.ggpht.com/ytc/AAUvwni2C4pmWWWjaxY2ZUnFjYqiyCpD3Y-mXhozkw=s64-c-k-c0xffffffff-no-rj-mo', 'width': 64, 'height': 64, 'id': '64x64'}], 'id': 'UCD-RwEzxUzl1MsSpc-AwMtw'}, 'message_type': 'text_message'}

I will be adding a lot of documentation soon! I just had to release this relatively unpolished version because of YouTube API endpoint changes.

Ohhhh it's now a generator, that's really great!
Thank you!
