Proposal for dynamically generated node pins

Thanks for the help @ThePywon!

/// Execute different branches based on string value.
///
/// This node matches the input string against several predefined options and executes
/// the corresponding branch for the first match. If the input does not match any option,
/// the default branch is executed.
///
/// # Inputs
/// - `value`: The string value to match against the options
///
/// # Execution Outputs
/// - `Option1`: Executes if value matches "option1"
/// - `Option2`: Executes if value matches "option2"
/// - `Option3`: Executes if value matches "option3"
/// - `Default`: Executes if no match is found
///
/// # Example
/// If `value` is "option2", the node will execute the code connected to `Option2`.
/// If `value` is "unknown", the node will execute the code connected to `Default`.
///
/// # Notes
/// You can customize the option strings and add more branches as needed.
/// # Switch on String
/// Routes execution based on a string value.
/// Matches the string against predefined options or executes the default branch.
#[blueprint(type: NodeTypes::control_flow, category: "Flow", color: "#BD10E0")]
pub fn switch_on_string(value: String) {
    match value.as_str() {
        array!({
            param!("Match Name", inner_value, String);
            inner_value => exec_output!(inner_value),
        }),
        _ => exec_output!("Default"),
    }
}

Reference material:

This would allow similar functionality to the dynamically pinned nodes in Unreal Engine but allowing for more complexity.
