Support simple class with BodySerializationMethod.UrlEncoded

The param is required to implement IDictionary, https://github.com/canton7/RestEase#url-encoded-bodies e.g.

Task Collect([Body(BodySerializationMethod.UrlEncoded)] Dictionary<string, object> data);

Refit can do this, see: https://github.com/paulcbetts/refit#form-posts e.g.

Task Collect([Body(BodySerializationMethod.UrlEncoded)] Measurement measurement);
// Serialized as: v=1&tid=UA-1234-5&cid=d1e9ea6b-2e8b-4699-93e0-0bcbd26c206c&t=event

Are there any reasons why RestEase doesn’t support this or is this just not implemented yet?

Nevertheless, this is an awesome lib! Keep up the good work!

Todo list:

1. Write code to serialise an object to a set of query params.
2. Add a new attribute allowing a name to be given to a property in such a class
3. Add a new type of serialiser allowing this behaviour to be customised. Move the existing dictionary serializarion code into this serialiser. Make sure we allow custom cultures, etc.
4. Refractor RequestInfo so that QueryMap can accept any object, and pass that object to the Requester.
5. Update Requester so that it calls the serialiser for QueryMap and serialised request bodies.
6. Consider whether to allow a format string to be used when serializinf property values.
7. Consider what to do with nested objects. Do we just call ToString on them, or do we try and serialise them? Changing this later will be breaking behaviour.
8. Tests. Cover non-public properties, abstract, no getter, getter throws an exception, getter returns a collection, getter returns null, getter returns an object whose ToString method throws. Nested objects if appropriate.
9. Document it all.

It’s not supported because I didn’t want to start going down the rabbit hole of writing a custom serializer! Those things get complex fast: I’ve done it before.

That said, it probably isn’t too hard to let json.net turn the object into a JObject, then munge that into a query string. I’ll have an investigate.
