Breaking change in expression parsing between versions 1.5.0 and 2.5.3

@vova-lantsov-dev Hi, I have tried to address this issue with pull request #355. It includes test cases for the scenarios you mentioned and the tests are now passing successfully.
If you have time, could you please review the changes in the PR?

Here are two questions:

1. The current transformer processing for Matcher does not recognize index operators, and this needs to be fixed.

   Casbin.NET/Casbin/EnforceView.cs

   Lines 121 to 122 in 5a358a4

   	string perfix = @"(?<=(\s|^|\||&|!|=|\(|\)|<|>|,|\+|-|\*|\/|\\)\s*)";
   	string suffix = @"(?=\s*(\s|$|\||&|!|=|\(|\)|<|>|,|\+|-|\*|\/|\\|\.|in))";

2. The overload used for Enforce is incorrect. Enforce currently supports generic parameters, which helps to avoid the significant overhead caused by forced boxing. You can try to make a direct call, like this:

var authorizationAttributes = new Dictionary<string, Dictionary<string, string>>
{
    ["CompanyData"] = new Dictionary<string, string>
    {
        ["CompanyIsActive"] = "True", ["BusinessRole"] = "Role1"
    }
};
result = _enforcer.Enforce(authorizationAttributes, role, path, method);
