Add option to output with filename for each error to allow for easy recognition of the locations by editors.

Hi @gigi-minds-ai , thank you for this contribution. This is a good idea.

Due to some weird bug of Github, I cannot contribute to this PR/branch. I had to open another PR (#119) to implement my additional changes.

I renamed the config option to --show-filenames-in-every-violation-message (shortform: -sfn), because -h is often used to print out the helper information of a command, and --heading is not self explanatory.

You can use this command to do what you'd like:

pydoclint -sfn=True .

(The default value is False.)
