-v, -version command doesnt work when deployed

Check if tool follow https://github.com/lirantal/nodejs-cli-apps-best-practices
if not - submit issue with suitable description

Readme needs updated documentation for all newly introduced commands

Add option for user to paste text directly into the shell, as alternative for specifying path

An option to allow setting the number of words to be shown

Update readme video with current state of project

There should be -version and -v command added that respond with current package version
This one should be implemented inside index.js file

Hey, I think CLI's UI needs some improvement. I would like to give it a try.

Create "stats" command:
syntax:
metaxa stats <path>
where is path to specified file for which user what to get statistic

Statistic to show:

• number of words
• number of sentences
• absolute path of file

Make code working overall better, faster

Instead of miliseconds we should measure delay by words per minute (wpm)

Please assign this issue to me with hacktoberfest lable. Thanks

Make arguments syntax compatible with POSIX-compliant

Add a CONTRIBUTING.md file with some basic contribution guidelines, how to setup project

Change colors to keep everything consistent.
One color for header and one for content

Provide better desciption of commands after -help is typed.
Include description for -version

Improve README.md with video showing working cli
