Custom prefix per short_url

[vpuentem]

Hi! first of all thanks for the package, it has been very usefull for me.

I recently had a use case where I needed to add a custom prefix per short_url to allow tenants add their own slug to make the url more readable and unique (example: https://myshortdomain.com/{customPrefix}/{urlKey})

I implemented the logic in my code and wanted to check if it is something anyone would use, so I maybe PR it to the repo.

To add a custom prefix to a shortUrl you can use a new ->customPrefix() method. Example:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->customPrefix('custom-prefix')->make();
$shortURL = $shortURLObject->default_short_url;

// Short URL: https://webapp.com/custom-prefix/random-key
