Added Search feature to Youtube Scraper

[OmarELRayes]

Added Search feature with keyword with a corresponding test using assertPosts.
Also fixed an issue where video's views would be in this format 150,100,100 format (with commas).
One problem we need to address that the views property in PostStatistics is Int? where there are videos that exceeds that limit, didn't want to change it as it's tightly coupled with the rest of the scrapers.

Thank you very much for your contribution! Really looking forward to this feature.

One little thing - current structure prefers common fetchPosts method with bunch of extensions for provider-specific scrapers, which incapsulates path and query params building. From my perspective it is quite relative case.
Regarding issue with Int restrictions - I haven't met yet cases when size exceeds integer boundaries, but if it is - it'a not a big deal to increase it up to long boundaries, sure. It possibly would break compatibility, but anyway this tool definitely will never have major first version due to specifics of scraping and changing document structure of data providers without any notice.

Love to contribute in such a good library and clean code!
I understand your point, I made it as a separate function to emphasis "separation of concerns" ( pardon if I'm mistaken, still a junior dev here :D ).
Can you elaborate more on what I need to change ?
the case is I need to the user to pass me a "keyword" value instead of a path because the path is pretty much stable "/results" then I add the keyword to the queryParams map.

Yes, I got your point.
You should just convert this public function to the extension function in YoutubeSkraperExtensions.kt.
Signature would smth like this (yes, I also should rename path param to urn):

fun YoutubeSkraper.getSearchPosts(keyword: String): Flow<Post> {
    return getPosts(path = "/results?search_query=${keyword.replace(" ","+")}")
}

And your function logic should be inside getPosts() to be capable of scraping both user videos and search results videos.

Thank you for elaboration, It's much cleaner now.
Hope you find it better.

Thank you, that's exactly what I meant!
It's merged.
