Support [PartParam] on object properties?

So that a single object could be sent as the method parameter and then parsed for parameters.

So that instead of having:

Task Request(
  [QueryParam] string a,
  [QueryParam("z")] string b,
  [QueryParam] string c,
  [QueryParam] string d,
  [QueryParam] string e);

We could have:

public readonly record struct RequestQuery(
  string a,
  [QueryParam("z")] string b, 
  string c, 
  string d, 
  string e);

Task Request([QueryParam, ParamObject] RequestQuery query);

Where ParamObject is a new attribute that tells Activout.RestClient to inspect the properties of the object and QueryParam specifies the (default) type of parameter for the object properties.

Maybe having a prefix parameter to ParamObject that adds a prefix to all parameters in the object? So that this code would generate query parameters named foo.a, foo.z, foo.c, etc.

public readonly record struct RequestQuery(
  string a,
  [QueryParam("z")] string b, 
  string c, 
  string d, 
  string e);

Task Request([QueryParam, ParamObject("foo.")] RequestQuery query);
