⚡️ Trend specific Unclogger configurations

[Rikj000]

To more aim for a 3 in 1 strategy (one setup for each trend) & after talking with @3ylo I think we can gain benefit by HyperOpting for 3 separate unclogger configurations, one for each trend.

The idea here is that the detected trend usually correlates to the expected amount of volatility of the crypto market.
(For example: sideways trend => less volatility then upwards or downwards trends)
Then we would be better off with 3 individual (for each trend) unclogger configurations.

Example output section of mgm-config-hyperopt after the implementation of this:
