Dynamic input specification that allows tasks to have a variable number of input ports.

This class enables tasks to accept a dynamic number of input resources that can be added or removed at runtime. All input resources are aggregated into a single ResourceList that is passed to the task under the name specified by SPEC_NAME ('source').

Dynamic inputs are useful for tasks that need to process an arbitrary number of similar resources, such as merging multiple files or combining multiple datasets.

Attributes: SPEC_NAME: The name of the input parameter passed to the task ('source'). This is the key under which the aggregated ResourceList will be available. additionnal_port_spec: Optional specification that defines the type and constraints for dynamically created input ports. If None, defaults to accepting any Resource type.

Example: ```python # Define dynamic inputs that accept Table resources inputs = DynamicInputs( additionnal_port_spec=InputSpec(Table, human_name="Input table") )

# In the task's run method:
def run(self, params: ConfigParams, inputs: InputsDTO) -> OutputsDTO:
    # Access all inputs as a ResourceList
    sources: ResourceList = inputs['source']
    # Process each table
    for table in sources:
        # Process table...
```
