feat: Refactor Registries

Interface changes:
- Rename StrategySelector to StrategyEncoderRegistry
- Implement clone for SwapEncoder

The StrategyEncoderRegistry needs to be initialised at the highest level and the passed to the TychoEncoder.
The TychoEncoder doesn't hold the chain nor the signer_pk as attributes anymore
The StrategyEncoderRegistry does:
- Initialises the SwapEncoderRegistry
- Initialises all the strategies and saves them in a HashMap
- Later, the TychoEncoder only reads from this hashmap

The StrategyEncoder now each holds a SwapEncoderRegistry as an attribute and they use this to get the correct SwapEncoder instead of reading from the global SWAP_ENCODER_REGISTRY

Simplified the SwapEncoderRegistry to not need a Config (everything is done inside itself)
All SwapEncoders implement clone
