EnemyRandomizer

Replaces normal and elite battle enemies with random enemies, based on act and weight value

Each enemy in the game is given a weight value based on difficulty.
The total weight of all enemies for this battle can not go over the maximum, based on the current act section.
Balance is still ongoing, and there may be behavioural issues with some enemies (I've had to disable Sunny since she softlocks the game)

For future

Add config to allow the act section maximum weights to be adjusted.
Add configs regarding allowing elites.
Other various misc things.
