Implement core

[ManiMozaffar]

Core functionality should be:

1. Implement Process (currently it's called Spider, but i think it makes more sense if we call it process since it's a process), for each crawling process.
2. Implement Crawler class
3. Implement the functionality of appending all those process, like a router configuration in fastapi.
4. Initiate all process to rocketry task to write print("Hello fastcrawler") on console, present it to a team member confirming your work in progress.
5. Implement the functionality of making request, in minimal version, no feature for now. let's KISS :)
6. Parse the result and print it on console. Catch all errors in memory for now if there's any.
7. Be friendly to uvicorn (async serve) to run the crawler with uvicorn.

This issue shall be started to work when schedule is merged
