Refactor CMORiser input parameter and add utility function for ocean file retrieval

- Updated the parameter name from `input_paths` to `input_data` in multiple instances of the ACCESS_ESM_CMORiser initialization within the Tutorial1 notebook.
- Introduced a new utility function `get_monthly_ocean_files` in `utilities.py` to facilitate the retrieval of ocean model output files based on CMOR variable mappings, including error handling and warnings for missing files.

+CMIP7 Support with Full Branded Names
+======================================
+
+ACCESS-MOPPy also supports the new CMIP7 compound name format, which uses full branded names instead of the table.variable format used in CMIP6. CMIP7 introduces a more descriptive naming convention that includes detailed information about the data processing and grid specifications.
+
+The CMIP7 format follows the pattern: ``realm.variable.operation.frequency.domain`` (e.g., ``atmos.tas.tavg-h2m-hxy-u.mon.glb``)
+
+This provides more explicit information about:
+
+- **Realm**: Model component (atmos, ocean, land, etc.)
+- **Variable**: The physical quantity  
+- **Operation**: Temporal and spatial processing applied
+- **Frequency**: Data output frequency
+- **Domain**: Spatial domain specification
+
+Using CMIP7 Compound Names
+---------------------------
+
+Here's how to use CMIP7 compound names with ACCESS-MOPPy:
+
+.. code-block:: python
+
+   # Example: CMIP7 compound name for atmospheric temperature
+   cmip7_cmoriser = ACCESS_ESM_CMORiser(
+       input_data=files,  # Can reuse the same atmospheric files
+       compound_name="atmos.tas.tavg-h2m-hxy-u.mon.glb",  # CMIP7 full branded name
+       experiment_id="piControl-spinup", 
+       source_id="pcmdi-test-1-0",  # CMIP7 test source identifier
+       variant_label="r1i1p1f1",
+       grid_label="gn", 
+       activity_id="CMIP",
+       parent_info=parent_experiment_config,
+       cmip_version="CMIP7"  # Explicit CMIP7 support
+   )
+
+   # Display the CMIP7 variable mapping
+   cmip7_cmoriser.variable_mapping
+
+CMIP6 vs CMIP7 Compound Name Comparison
+----------------------------------------
+
+The table below shows the key differences between CMIP6 and CMIP7 compound name formats:
+

+
+   * - Aspect
+     - CMIP6 Format
+     - CMIP7 Format
+   * - **Structure**
+     - ``table.variable``
+     - ``realm.variable.operation.frequency.domain``
+   * - **Example**
+     - ``Amon.tas``
+     - ``atmos.tas.tavg-h2m-hxy-u.mon.glb``
+   * - **Information**
+     - Table and variable only
+     - Detailed processing and grid info
+   * - **Length**
+     - Compact
+     - More descriptive
+
+**CMIP7 Compound Name Breakdown:**
+
+- ``atmos``: Atmospheric realm
+- ``tas``: Near-surface air temperature  
+- ``tavg-h2m-hxy-u``: Time-averaged, 2-meter height, horizontal grid, unstructured
+- ``mon``: Monthly frequency
+- ``glb``: Global domain
+
+ACCESS-MOPPy automatically handles the mapping between these formats and the underlying model variables.
