In essence, they are `[]byte` -> `[]byte, error` functions.

It is not possible to return *both* an error and a response.

Handlers are registered on the manager using `(*Manager).RegisterSingleHandler(id HandlerID, h SingleHandlerFn, subroute ...string)`.

The server handler function has this signature: `type SingleHandlerFn func(payload []byte) ([]byte, *RemoteErr)`.

Sample handler:
```go

        // Prepare buffer with specific type value
        testBuffer[0] = 0x01; // revision
        testBuffer[1] = 0x00; // padding
        testBuffer[2] = 0x04; // type low byte
        testBuffer[3] = (byte) 0x80; // type high byte (0x8004)
        // Set all offsets to 0
        for (int i = 4; i < 20; i++) {
            testBuffer[i] = 0;
        }
