Make it clear that this only needs the CAS-oriented Get and not the full walker. Signed-off-by: W. Trevor King <wking@tremily.us>

Both of these calls are to descriptor.validate(), which only needs a reader. Signed-off-by: W. Trevor King <wking@tremily.us>
This is only getting CAS blobs, so we only need a reader. And there's no need to locally implement Get. Signed-off-by: W. Trevor King <wking@tremily.us>
Now that we've ported manifest.unpack over to reader, we can replace the more-complicated walker implementation (which also provides for mutable-ref access) with the more-basic reader (which only interacts with CAS blobs). Signed-off-by: W. Trevor King <wking@tremily.us>

Start distinguishing between
reader(when you only need toGetCAS blobs) andwalker(when you might also need to access mutable refs). This lays the ground work for something like #5, but avoids the contentious invention of new interfaces by sticking to interfaces which have already landed in master. Also removes a number of redundantGetre-implementations.
