Tiktokapi

Seems like the discover methods are no longer working as frequently if at all with the `use_test_endpoints=True`, look at the diff for this pr (603 ) specifically in the test files to see the methods that seem to be affected the most.

Also generate_did has been moved to a static function.

(also the tests are passing on my machine just not GitHub actions because they're not on residential IPs some of the errors might be transient)

Merged
* 577
* 578
* 580

See 586 for methods that currently aren't working

I've also joined the brave browser rewards so if you want to feel free to tip me if you use brave browser using your BAT

Things were fixed 😄

* discover methods fixed
* byUsername & other HTML requests fixed

Changes
* Updated documentation for custom_did
* custom_did is maintained at the instance level if set
* generate_static_did added as a parameter to the TikTok constructor. If set to True it will generate and maintain a static custom_did so you don't have to do it yourself.
* Added generate_did method which returns a valid did which you can use however you want.

This package has spent too long having its documentation listed in the readme of all places. I'm excited to announce that I've added a new auto-documenting part to the codebase. Hopefully, that makes this package that much more easy to deal with

**Naming Scheme**
* All the methods have moved from camelCase to snake_case as it's annoyed me for a bit
* BUT don't worry it's backward compatible and I intend to keep it that way for at least awhile

The last time I did this it was super effective so please connect with me on [LinkedIn](https://www.linkedin.com/in/davidteather/) if you're reading this. I'm just a 1st year in college and anything helps, plus I spent like 3.5 hours on this update on a Sunday night.
