final data have redundant tweets

[sepehrity]

Thanks for your great work!

The getTimeline and getLiked functions get redundant tweets. Related to Twitter API docs, I think we should use since_id and max_id together to fix this.

function	count	without duplicates
getLiked	3164	2943
getTimeline	3415	3202

I haven't had time to look at this yet but I am not sure what's happening but IDK if since_id would fix the issue.
For the getTimeline I am guessing a lot of duplicates could be appearing due to a user both retweeting and commenting on a post, for the liked, I am really not sure.

According to the docs, since_id is used to fetch new posts since and id, but the way the pagination works here is going down the chronological order rather than up.
