SwapStyle enum serialization is incorrect

[tanczosm]

The current serializer for SwapStyle uses JsonNamingPolicy.CamelCase, which converts SwapStyle.AfterBegin to "afterBegin" instead of the correct "afterbegin". This issue impacts several enum values.

That's an easy fix. Create a SwapStyleConverter : JsonConverter<SwapStyle> in the serialization folder and register it with the sterilization context.
