Added translation feature

[therealzanfar]

Basic translation feature implemented.

Main changes:

• Added --translate CLI option
• Added translation logic and helper functions
• Added additional debug logging output
• Added translation tests and pytest support
• Updated README.md

Other changes:

• My workflow is a bit different, which created many ancillary files that are not in your .gitignore, so I just appended the toptal boilerplate I use.
• Added shebang so that the script can be executed directly
• I tried to silence my auto-formatting as much as possible. I don't think I introduced any unrelated changes, but if so, I apologize

Should close #26

This worked perfectly for me, important to remember is just that you have to add a '/' to the end of the path mappings :) Thank you
