Breaking changes around responseTransformer!

In this PR #165, we realized that the responseTransformer feature added last release wasn't broad enough, responseTransformers now receive the raw response stream instead of just the json()-promise.

Code which relies on this feature will break, however the fix should be very simple:

Either the responseTransformer function is made `async` and to `await response.json()`, *or* if this syntax is not available, the existing code needs to be wrapped in `response.json().then(data => {/* existing implementation */})`.
