Release v0.2.0

In this release, we have modified the representation model to some (in breaking ways) extent and there are now new APIs for working with custom types.

• Create CustomClassDefinition from a given C# class using reflection
• Create CustomEnumDefinition from a given C# enum using reflection
• Map properties to given C# class using reflection
• Add Loader class with in-memory caching by default
• Models that have a class (or in some cases type) property will now use that custom type to populate their properties, like in Tiled
• TiledCSPlus is unfortunately no longer maintained, reflected in README
• TiledLib TiledLib now released for .NET 8, reflected in README
• Optional properties in representation model now wrapped in a Optional<T>, instead of using Nullable
• Several docs fixes
• ObjectLayer visible property in TMX parser was incorrectly bool instead of uint
