feat: Add globMatch to BuildInFunctions

[dviry]

Using Casbin.NET v1.11.0 - getting the following error when trying to use globMatch() as a matcher:

DynamicExpresso.Exceptions.UnknownIdentifierException: 'Unknown identifier 'globMatch' 

In the past I've used DotNet.Glob - can we integrate it as a built-in function?

Thanks in advance

PS: currently I'm adding it dynamically to the Enforcer instance:

enforcer.AddFunction("globMatch", (string key1, string key2) => Glob.Parse(key2).IsMatch(key1));
