YAML refactor + improved tweets + question filters

[edomt]

Hey @nikosbosse!

I ended up putting a bunch of things in the same pull request, sorry about that!

• Easier config: the YAML file now stores:
  • the list of questions
  • the thresholds above which a tweet is sent (+5% in 5 hours or +10% in 24 hours)
  • filters that exclude questions as suggested in https://github.com/nikosbosse/Metaculus-Twitter-bot/issues/5. For now, they're set so that questions must be at least 24 hours old, and have at least 10 forecasts.
• I've refactored get_predictions.py a little to use more methods inside the main class, and process the time series as a data frame
• add_tweet() handles the "writing" of the tweet, with something close to the suggestion in https://github.com/nikosbosse/Metaculus-Twitter-bot/issues/3
• I've added more print statements for easier debugging, but of course, feel free to remove anything that's not needed

Generated tweets now look like this:

Will Vladimir Putin and Volodymyr Zelenskyy meet to discuss the peaceful resolution of the Russian-Ukrainian conflict? 🔼 Community prediction: 45% +14% in the last 24 hours https://www.metaculus.com/questions/10046/ukraine--russia-presidential-peace-talks/

Great! I'm able to run all Python files locally, but without deploying to GCP or sending the actual tweet to the Twitter API. But that's probably enough on my side to be able to help :)

Thank you very much! Merging this :)

I thought about changing your up / down button to an arrow: ⬆️ do you have thoughts on that? It would be more consistent with the current profile picture - but I don't have a very strong preference.
