Consider adding ChoCSVRecordFieldConfiguration<T>

[HoangTangUta]

Please consider adding a generic version of ChoCSVRecordFieldConfiguration since a generic version of WithField already exist on the reader.

So after a good night sleep I figure a better way to solve it for myself that support strongly typed mapping. Feel free to incorporate this code however you see fit.

public class CSVTransformer<T> : ChoCSVRecordConfiguration
    {
        public CSVTransformer<T> Map<TProperty>(Expression<Func<T, TProperty>> property, string fieldName)
        {
            CSVRecordFieldConfigurations.Add(new ChoCSVRecordFieldConfiguration(property.GetMemberName(), 0)
            {
                FieldName = fieldName,
            });
            return this;
        }
        public Action<T> AfterRecordLoad { get; set; }
    }

I intentionally name this different than ChoCSVRecordConfiguration in case you wish to make ChoCSVRecordConfiguration<T> this will not break my code.

Here are the example usage

public class ChoGenericMapperTest
    {
        public class Emp
        {
            public string Name { get; set; }
            public string Other { get; set; }


            public string MyId { get; set; }
        }

        [Test]
        public void TestMapping()
        {
            string csv = @"Id, Name, City
1, Tom, NY
2, Mark, NJ
3, Lou, FL
4, Smith, PA
5, Raj, DC
";

            ChoCSVRecordConfiguration config = new ChoCSVRecordConfiguration();
            config.CSVRecordFieldConfigurations.Add(new ChoCSVRecordFieldConfiguration("MyId", 0)
            {
                FieldName = "Id",
            });
            config.CSVRecordFieldConfigurations.Add(new ChoCSVRecordFieldConfiguration("Name", 0)
            {
                FieldName = "Name",
            });
            config.CSVRecordFieldConfigurations.Add(new ChoCSVRecordFieldConfiguration("Other", 0)
            {
                FieldName = "City",
            });
            config.WithFirstLineHeader(false);

            using (var reader = ChoCSVReader<Emp>.LoadText(csv, Encoding.ASCII, config))
            {
                reader.AfterRecordLoad += (sender, args) => { };
                Console.WriteLine(reader.ToList().DumpAsJson());
            }
        }

        [Test]
        public void TestNewMappingMethod()
        {
            string csv = @"Id, Name, City
1, Tom, NY
2, Mark, NJ
3, Lou, FL
4, Smith, PA
5, Raj, DC
";

            var config = new CSVTransformer<Emp>();
            config.Map(emp => emp.Name, "Name");
            config.Map(emp => emp.Other, "City");
            config.Map(emp => emp.MyId, "Id");
            config.WithFirstLineHeader(false);

            using (var reader = ChoCSVReader<Emp>.LoadText(csv, Encoding.ASCII, config))
            {
                reader.AfterRecordLoad += (sender, args) => { };
                Console.WriteLine(reader.ToList().DumpAsJson());
            }
        }



    }

Added support of this feature in 1.0.2.1-alpha1 package

Pls try and let me know
