Implement post reply functionality

[yeenbean]

The bot currently lacks the ability to respond to posts. It is necessary to implement this feature, along with a dedicated file named "reply_file.txt" to store the replies.

What if it works like a cron job. It looks for tweets each heartbeat (or literal cron job) and replies to the tweets within that time? It theoretically should not respond to anything it has already replied to since it will happen each minute on the minute and not look for post beyond the previous minute...

Alternatively, and this should work well with mastodon at the very least, we implement streaming so that pauljac can reply to things in realtime.
