146148c48c Refactor SAC configuration and policy for improved action sampling and stability 
- Updated SACConfig to replace standard deviation parameterization with log_std_min and log_std_max for better control over action distributions.
- Modified SACPolicy to streamline action selection and log probability calculations, enhancing stochastic behavior.
- Removed deprecated TanhMultivariateNormalDiag class to simplify the codebase and improve maintainability.

These changes aim to enhance the robustness and performance of the SAC implementation during training and inference.

8f15835daa Refine SAC configuration and policy for enhanced performance 
- Updated standard deviation parameterization in SACConfig to 'softplus' with defined min and max values for improved stability.
- Modified action sampling in SACPolicy to use reparameterized sampling, ensuring better gradient flow and log probability calculations.
- Cleaned up log probability calculations in TanhMultivariateNormalDiag for clarity and efficiency.
- Increased evaluation frequency in YAML configuration to 50000 for more efficient training cycles.

These changes aim to enhance the robustness and performance of the SAC implementation during training and inference.

022bd65125 Refactor SACPolicy for improved action sampling and standard deviation handling 
- Updated action selection to use distribution sampling and log probabilities for better stochastic behavior.
- Enhanced standard deviation clamping to prevent extreme values, ensuring stability in policy outputs.
- Cleaned up code by removing unnecessary comments and improving readability.

These changes aim to refine the SAC implementation, enhancing its robustness and performance during training and inference.

6db2154f28 Enhance SAC configuration and policy with new parameters and subsampling logic 
- Added `num_subsample_critics`, `critic_target_update_weight`, and `utd_ratio` to SACConfig.
- Implemented target entropy calculation in SACPolicy if not provided.
- Introduced subsampling of critics to prevent overfitting during updates.
- Updated temperature loss calculation to use the new target entropy.
- Added comments for future UTD update implementation.

These changes improve the flexibility and performance of the SAC implementation.
