Feat: store conversation in database instead of in-memory map object

[purerosefallen]

To make conversations survive between Koishi restarts, it could be better to store the conversation IDs into database instead of a memory map.

Maybe we should also consider instances that has no database enabled, how to deal with them?

Can you provide some minimal example or workaround?

You may use .userFields to observe user, and do the talk. if user does not exist, fallback to the map thing.
Plus, if you think instances without database should be considered, so do other plugins such as github, or teach.

Now that Cache API being a thing, how about that one?

I'll take a look when I have time.
