 PSR-7 compliant, immutable adapter interfaces for SilverStripe HTTP classes.

 From here you can use any of the PSR-7 interface methods, and the results will always be immutable:
 
 ```php

 $newResponse = $response->withHeader('Content-Type', 'application/json');
 $newResponse = $newResponse->withHeader('X-Custom-Header', 'my-value-here');
 
-// $response !== $newResponse
+// $response !== $newResponse -> #psr7-ftw
 ```
 
 The same concept applies to the `HttpRequestAdapter`, for example:
 
 ```php
