Is your feature request related to a problem? Please describe.
It would be great if we could specify the process and shortcut AppUserModelID, instead of it being hardcoded to velopack.AppName. We already have an AppUserModelID that we use across different apps and it would be nice if it was not tied to Velopack.

Describe the solution you'd like
Allow specifying the AppUserModelID as an argument to vpk.

Describe alternatives you've considered
Don't think there is any other alternative, other than accepting that the AppUserModelID will be velopack.AppName when using Velopack and changing other things to match it.
