Distribute as PHAR

[feamsr00]

Is your feature request related to a problem? Please describe.
It's not as easy to keep and shuffle around composer global tools as it is PHAR tools.

Describe the solution you'd like
It would be great if you folks could distribute this as a PHAR app.

Additional context
I've used box-project/box a great deal and it's an easy way to get started.

Tried it out on the spur of the moment and it was pretty effortless:

> composer create-project Comcast/php-legal-licenses pll
Creating a "Comcast/php-legal-licenses" project at "./pll"
Info from https://repo.packagist.org: #StandWithUkraine
Installing comcast/php-legal-licenses (v1.2.0)

> cd .\pll\
>box compile
