I had the a similar issue when trying to add the package to a laravel-zero application (conflict with Illuminate packages).

Moving to require-dev should allow the same development experience while not forcing a full install of the laravel framework when adding to a laravel-zero project.

I don't believe this is the right fix. Including full Laravel was probably a mistake, but I see 4 occurrences of Illuminate.

use Illuminate\Console\Command;
use Illuminate\Contracts\Support\DeferrableProvider;
use Illuminate\Support\ServiceProvider as BaseServiceProvider;
use Illuminate\Support\Facades\Facade;

So we could probably isolate down to Console, Contracts and Support.

Console could probably be dev, as its only used in the install command.
