ExcelPackage.Configure does not set IConfiguration for license info.

This should work:

var configuration = new ConfigurationBuilder()
    .SetBasePath(Directory.GetCurrentDirectory())
    .AddJsonFile("jsconfig1.json", optional: false, reloadOnChange: true)
    .Build();

ExcelPackage.Configure(options => options.Configuration = configuration);

var p = new ExcelPackage();
