Added Bacon Cipher

[ghSP]

What is a bacon cipher? (copied from Geocaching Toolbox with spelling corrections)

The baconian cipher is a method of stenography. Stenography is the art of writing hidden messages in such a way that no one suspects the existence of the message. In case of the baconian cipher, each letter is encoded with a series of 5 characters consisting of a number of A's and B's.
However, in a text encoded with this cipher, you will never see these series of A's and B's. They are hidden within a text. An example is the coding through typeface, for example normal and italic letters. The normal letters represent an A and the italic letters represent a B. By this way one can hide a secret message in an on first sight normal text.

I have added a Baconian Cipher into the index.js files, added the 'characters' to a variable in the utils file and have create the actual cipher with the same design as the other cipher-files.

One thing I am not sure how to do is add tests/coverage for the bacon cipher. If you could let me know how to do this and what format you would prefer it be in I would be more than happy to do that.

Coverage remained the same at 100.0% when pulling 522c0bd on yaas-dev:feature/bacon-cipher into f64c59a on sheharyarn:master.

To increase coverage, I can write tests for decrypt/encrypt Bacon cipher. I would just need criteria for each method to meet in order to increase that coverage from 9.38 to 100 percent

I looked at the cli.js file and I couldn't figure out how to add the bacon cipher into it. 😃
