Prepare for Laravel 6.1

[Ricardo Čerljenko]

Please raise the version flags for Laravel 6.1+

[Владислав Сердобинцев]

Please fix bug with custom Blade directives!!!!

[Timon Weber]

With #139 there is already an open PR which would resolve this issue by allowing all non-breaking future versions of laravel/framework (< 7.0.0).

@timonweber this would be great because there's Laravel 6.2 already and I'm sick of waiting every time there's a new Laravel version for this package to update...

[Rasmus Jensen]

Any chances this will be updated for the current version 6.3?

[Raza Mehdi]

Package has been updated to support Laravel 6.1 & beyond.
