Adding yargs and support for -p,--profile to use named profiles in .aws/credentials

[drmikecrowe]

This add support for named profiles.

Sorry about the formatting change -- vscode + prettier are insistent. I tried to revert and go back to your format, but turning the main code into a function hit almost every line anyway.

Example:

$ ./bin/aws-console -h
Usage: aws-console [-p profile_name]

Options:
  --profile, -p  Use named profile in .aws/credentials                  [string]
  --version      Show version number                                   [boolean]
  -h, --help     Show help                                             [boolean]

$ ./bin/aws-console --version
1.0.3

Hi @drmikecrowe ! Thanks for the PR!

Adding support for aws named profiles is a great addition and I was planning on adding it. Unfortunately, I am not accepting any PRs (Pull Requests) at the moment. the package is still WIP and until I open the project for contribution and add a code of conduct, I'd recommenced requesting new feature via the issues section https://github.com/minayousseif/aws-console/issues.

Thanks again
