New "creator" API for user post extraction

[antiops]

There is a new API that was added that currently doesn't require any signatures to get user posts.

It was recently implemented and tested in the TTUser yt-dlp plugin (Implementation: tt_user.py) with some extra notes available in Issue 1

The bare minimum parameters are:

• secUid
• count can be max 15
• cursor with current time in milis will return the most recent posts
  • Follow up cursor uses last post in the item list
  • Cursor 0 returns the oldest posts
• verifyFp can be anything as long as it starts with verify_
• aid & type dont change

Examples:

TikTokPy currently uses the /post/item_list/ endpoint, which seems to be incredibly similar to this endpoint, just with the extra need for an X-Bogus parameter (it also lets me grab 30 at a time). I'll keep an eye out to see if the endpoint I'm currently using stops working, but at the moment I'm not sure it's worth switching over.
