[FEATURE REQUEST] The macro pipeline execution should stop when an error is raised.

[petitpandarouge]

Is your feature request related to a problem? Please describe.
When an error is in a script, I would like it to stop the pipeline execution.
It is specially disturbing when dealing with variable.
If the next step takes a variable filled by the previous script, because of the exception, the variable is not filled, and the next step display a popup asking for the variable.

Describe the solution you'd like
If an error is raised, I would like to have to possibility to say to the pipeline to stop.
I think about like a "stop" property on the "params" variable.
If true, pipeline stops, if false, pipeline continue and popup displays.

Additional context
Step to reproduce :

• create a "test" macro
  
• copy this code into a "script.js" file accessible by QuickAdd

module.exports = async (params) => {
    params.variables['test'] = "this is a test";
};

• in the macro, add the script and a capture choice
  
• define the "test" variable as file name of the capture
  
  Everything works fine.
• raise an error in the script

module.exports = async (params) => {
    throw new Error("my error");
    params.variables['test'] = "this is a test";
};

• when executing the macro, the error is raised and the file name is asked.
