save test results to csv

[radlinskii]

Would be really useful to save results of the test that has run into a file so that results can be displayed and compared later on.

This issue is only about writing to a file.
File location can be, ~/.config/donkeytype/results.csv, because this folder is already used for config file.
.csv seems to be the best extension for this purpose.
If the file doesn't exist it should be created.

Different values that are currently displayed in src/main.rs after the test is finished should be added as columns into the csv.
Information about settings should also be included, (currently only duration, and numbers if numbers where present). Later might be beneficial to have this data for filtering the results.

serde crate should be used for this purpose, it is already a dependency.

There is no error here. This issue is about implementing the feature of writing the results that you get at the end of the main function

donkeytype/src/main.rs

Lines 97 to 113 in 3e2b48c

	Ok(stats) => {
	println!("WPM: {:.2}", stats.wpm);
	println!("Raw accuracy: {:.2}%", stats.raw_accuracy);
	println!("Raw valid characters: {}", stats.raw_valid_characters_count);
	println!("Raw mistakes: {}", stats.raw_mistakes_count);
	println!("Raw characters typed: {}", stats.raw_typed_characters_count);
	println!("Accuracy after corrections: {:.2}%", stats.accuracy);
	println!(
	"Valid characters after corrections: {}",
	stats.valid_characters_count
	);
	println!("Mistakes after corrections: {}", stats.mistakes_count);
	println!(
	"Characters typed after corrections: {}",
	stats.typed_characters_count
	);
	println!("Time: {} seconds", duration);

to a file so that they can be displayed later on.
