do we really need to console.error here? won't controller.error be enough?

can't we do the same streaming behavior using Response::chunk method, instead of pulling another crate to iterate over the stream?

This PR changes the internals of the fetch implementation such that
fetch_read_bodyuses theChannelAPI to stream http responses instead of waiting for the entire response to finish and then returning the final ArrayBuffer.Two things to note:
The
Channel<&[u8]>type is serializing as anumber[]instead ofArrayBufferorUint8Array. I'm not certain that the Channel supports serializing asArrayBuffers? I think this could be a possible performance improvement.The
ChannelAPI implementation does not guarantee that all events are received by the time theinvokepromise is resolved. This is unfortunate, but I worked around it by returning an empty array over theChannelwhich is used to close theReadableStream. I think this design works alright, but maybe there's a cleaner way to do this.Fixes #2129
