Add a GUI so user can choose limit an amount of threads

[Nyumat]

• Need to add a GUI so the user can limit the amount of threads to use.
• This is most likely a future problem for the repo, because right now I can limit it in line, but purely for the sake of a larger exploit its definitely needed.

I need to update setup.py to include a installation of one of the mainstream python GUI libraries and add a variable in the TikTokBot class to store the threading limit.

I'm not all that experienced with python yet, so i'll definitely have this issue up for some time to develop something that can work.

IMO, if you're thinking of contributing, please consider importing something lightweight like DearPyGui because most of the mainstream ones like Tkinter or PyQT would add over ~50 LOC in implementation--and we'd want something fast.
