fields not supported

[pavlexander]

Issue description

is there an apparent reason why fields are not supported?

For example when saving the data:

       var toSave = new List<MyParquetTest>
            {
                new MyParquetTest()
                {
                    Name = 0
                }
            };
            string file = @"D:\temp\performanceTests\test.parquet";
            await ParquetSerializer.SerializeAsync(toSave, file);

it will work just fine for the following class file with properties

       public class MyParquetTest
        {
            public int Name { get; set; }
        }

but for the struct with fields

        public struct MyParquetTest
        {
            public int Name;
        }

exception is thrown

System.ArgumentException: at least one field is required (Parameter 'fields')

would it be possible to add fields support? I feel like this is a needed feature, especially in the context of structs which by default usually do not contain properties.

Technically there's no reason, mostly lack of time ;)
