Refactor analyzers which download external dbs for local queries

[mlodic]

There are several analyzers like Tor, Maxmind, JA4DB and so on, that download an external db and update it every once in a while.
The problem is that they store it as a local file and the analyzers parse those files in search of a specific entry.
It would make sense to store them as additional tables in the database and to query the data directly there.
