The problem with the blob optimization here is that its different semantics to a ReadableStream.  A blob you can random access read in any order, etc.

What if we just added some kind of "skip" operation to ReadableStream?  This would let you efficiently seek forwards to the part you want without necessarily loading it all into memory.
