Goblin-lite

Added
- Spared area category totals. These are from the land use assignment module and they are outputed
automatically with every scenario run.
- Grass yield per hectare, output as part of the main scenario generation.
- Ability to pull down tables related to actual areas afforested.
- New grassland production support with `grassland_production` version 0.3.6.
- Passing a resource/context manager to the model, rather than a list of parameters and paths.

Changed
- Updated CI/CD workflows to include integration testing for `landcover_assignment` package with `goblin_lite`.
- Enhanced `land_distribution` logic to better handle rewetted organic areas.
- Updated documentation and examples to reflect the new changes.
- Updated the testing suite to cover new functionalities.

NOTE
- Package is compatible with `landcover_assignment [0.4.0]`, which now uses pyomo to optimise land distribution.
- Package is NOT compatible with `goblin_cbm_runner [<0.5.0]`.
