Installation issue

[spekulatius]

I've just tried to install the latest version and found my PHP having an issue:

peter@x1:/tmp$ packr -v
Composer detected issues in your platform:

Your Composer dependencies require a PHP version ">= 7.3.0". You are running 7.2.24-0ubuntu0.18.04.6.

The composer.json for packer says 7.2.5. I guess a dependency causes this. I'll open a PR to clarify it in the composer.json.

Cheers,
Peter

This way it would throw a message/warning, if the PHP version is incompatible.
