Auto recognize the maximum level of expedition, gauntlet, invasion

Is your feature request related to a problem? Please describe.
The bot always hang and stuck in some kind of loop if difficulty level in the setting file exceed the maximum difficulty level in game.

Describe the solution you'd like
If the user set the difficulty level in the setting file larger than the maximum difficulty level in game then the bot would recognize that and change the difficulty level to be the maximum difficulty level.

I had some internal builds for this (pushing max level) but they weren't very pretty. I'll see if I can provide a clean way of doing it for the bot.

The logic was already there for trials/gauntlet, I've now added it for expedition. Some tweaks are still probably needed as the level can be increased with the successThreshold configuration parameter.
