Create executable program

[denvaar]

Use escript to create an executable version of this program.

Might be useful: https://elixirschool.com/en/lessons/advanced/escripts/

Please add some command line options. For example, I am thinking something like

$ base64 --encode <path_to_input_file> <path_to_output_file>
$ base64 --decode <path_to_input_file> <path_to_output_file>

etc.
