### Typed handlers

Typed handlers are handlers that have a specific type for the request and response payloads.
These must provide `msgp` serialization and deserialization.

In the examples we use a `MSS` type, which is a `map[string]string` that is `msgp` serializable.

```go
    handler := func(request *grid.MSS) (*grid.MSS, *grid.RemoteErr) {
        fmt.Println("Got request with field", request["myfield"])
        // Do something with payload

	// 1: Echo
	h1 := NewSingleHandler[*MSS, *MSS](handlerTest, NewMSS, NewMSS)
	// Handles incoming requests, returns a response
	handler1 := func(req *MSS) (resp *MSS, err *RemoteErr) {
		resp = h1.NewResponse()
		maps.Copy((*resp), *req)
		return resp, nil
	}
	// Return error
	h2 := NewSingleHandler[*MSS, *MSS](handlerTest2, NewMSS, NewMSS)
	handler2 := func(req *MSS) (resp *MSS, err *RemoteErr) {
		defer req.Recycle()
