Modified app.js to return object instead of writing to file; moved code to write to file to cli.js

[SenecaAnderson]

Summary

The function mcodeApp in src/cli/app.js was modified to return the extractedData object instead of writing the results to a file. src/cli/cli.js was modified to write the results of calling mocdeApp to a file.

New behavior

cli.js writes the results of extraction to a file instead of app.js.

Code changes

The code to write to a file was moved from app.js to cli.js and replaced with a return statement.

Testing guidance

Use 'npm start' to run extraction.

I see there are some linter errors being caught by Github actions here. We have a pretty strict linter set up in the MEF, which allows us to enforce code style and make sure the syntax is correct.

You can configure VS Code to show you the lint errors by installing this extension: https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint

Once you do, you should see some errors in the editor that should need to be resolved. You can also check lint locally with the npm script we've added:

npm run lint

We also have a command that will fix and automatically fixable lint issues:

npm run lint-fix

Other than the lint errors and the change request I made, this looks good and works as expected

Looks great!
