Reader instead of File

[Houski]

Would it be possible (and a good idea?) to change the required File type to Reader here?

pub fn new_from_pre_trained(file: &mut File) -> Result<Self, io::Error> {

So something like this can be performed:

let faux_model_file = include_str!("./perform_contact_spam_filter_model.json");
 
 let classifier = Classifier::new_from_pre_trained(&mut std::io::Cursor::new(faux_model_file)).expect("Failed to load spam filter model");

Without the need to touch the file system?

It seems like it should take something more like a &str, and then the user is responsible for however that &str gets to the function.
