## Summary by CodeRabbit


- **New Features**
- Introduced new descriptor classes `DescrptSeTTebd` and
`DescrptBlockSeTTebd` for enhanced molecular simulation capabilities.
- Added advanced configuration options with `descrpt_se_e3_tebd_args` to
customize descriptor behavior.
- Launched the new `"se_e3_tebd"` descriptor for improved atomic
configuration representation.

- **Bug Fixes**
- Improved integration of new descriptors into existing test frameworks,
ensuring consistent functionality across multiple backends.

- **Tests**
- Implemented a comprehensive testing suite for `DescrptSeTTebd`,
validating its performance across various configurations and frameworks.

- **Documentation**
- Updated public API documentation to include newly added descriptor
classes and parameters for clarity and usability.
- Created a detailed guide for implementing the `se_e3_tebd` descriptor
in training models.

- **Chores**
- Added a structured configuration file `input_torch.json` for model
training and evaluation.
  - Expanded test examples with the inclusion of a new input file path.
