Support for Sink config from appsettings.json

[alastairtree]

Hello - thanks for the library.

I was wondering if you support reading the sink config from the configuration files using Serilog.Settings.Configuration? I can't seem to get the code below to add the sink? Am I doing it wrong or is it not supported? Or could you point me to some docs?

appsettings.json

"WriteTo": [
      {
          "Name": "EventCollector",
          "Args": {
             "splunkHost": "https://myhost/services/collector",
             "eventCollectorToken": "0000"
          }
       }
    ],

program.cs

Log.Logger = new LoggerConfiguration()
                .ReadFrom.Configuration(configuration)
                .CreateLogger();

@alastairtree there is a working version of this in #92.

What you have above seems correct. Make sure that your appsetting.json is available

var configuration = new ConfigurationBuilder()
    .SetBasePath(Directory.GetCurrentDirectory())
    .AddJsonFile("appsettings.json")
    .Build();

Log.Logger = new LoggerConfiguration()
    .ReadFrom.Configuration(configuration)
    .CreateLogger();
