Update composer for latest versions of Laravel

I'm trying to get this driver running since the official Botman driver for Discord is really outdated. When I require this via composer I get this error:

```
Your requirements could not be resolved to an installable set of packages.

I'm running Laravel 6.2.x and this package seems to have a hard requirement for a lower version. Could this be fixed? It would be very much appreciated.
