A BitTorrent 1.0 client implementation in Python

This is a project which I decided to tackle after toying around with BitTorrent for awhile. It's a second iteration where I tried to make it a bit tidier and extensible using preferably only the Python standard lib. In the end I needed to use external libraries, to mention:

• aiohttp to support concurrent HTTP requests
• bitarray to support a fast and light bitarray implementation in C

Currently supported features:

• - HTTP Trackers
• - Single file torrents
• - Multi file torrents
• - UDP Trackers
• - Seeding

I will hopefully work on UDP Trackers and seeding, as it isn't super complex to be incorporated, multi file torrents might require a bit more work however.

For UDP Trackers the great deal is finding a concurrent library capable of doing DNS queries and async UDP sockets, which might aswell be built from the ground up given it's simplicity.

Running this on a Python version < 3.11.7 will emit some warnings, newer versions fixed this.
