Fix output format with prettier

[Pustur]

Description

I saw that prettier was already a dependency of the project so I decided to use it programmatically to automatically format the output files.

I decided to create a new file in the utils/ folder so that if the function needs to be updated we can do it in a single place.

After the change a couple parts of the code would throw errors, but I fixed them in different commits so it should be easier to understand. If you need more info on my fixes please feel free to ask.

I hope you like this approach.
