Enable Git LFS for large files

Added:

- Added mathematical notations to the constraint module.
- Added a test script for `prepshot.utils`.

Fixed:

- Fixed the format of the API reference.
- Fix code blocks of documentation
- Updated `Contribution.rst` to include context on running tests and code style checks.
- Defined explicit data types for inputs and outputs of functions for better type checking and readability.
- Added `pyoptinterface._src.core_ext` to Pylint's extension package allow list to resolve cpp-extension-no-member warning.

Changed:

- Updated `model.py` to keep necessary decision variables and use expressions for intermediate variables instead of direct determination.
- Refactored `extract_results_non_hydro` in `output_data.py` to extract common features for different variables, simplifying the code.
- Removed definitions of complex sets and opted for simple sets wherever possible to streamline the code.
- Refactor: Organize import order of modules according to PEP 8 guidelines: (1) Grouped standard library imports at the top; (2) Followed by third-party library imports (3) Local application/library imports at the bottom
