feat: allow importing all items of a module with *

[enitrat]

Feature Request

Describe the Feature Request

Allow this feature:

fn f(){}
fn h(){}

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn test_f(){
       f()    
    }
 }

This would reduce a lot the amount of LOC required to simply have all the required items to perform unit tests. The requirement to handle manually all imports to day is a deterrent to implement a proper module-based structure for unit tests
