fetch() upload streaming

Fetch upload streaming lets web developers make a fetch with a ReadableStream body. Fetch provides a generic definition of Request and Response objects (and other things involved with network requests).

Motivation

Traditionally uploading byte arrays were implemented on WebSocket but it has made client/server code messy. Fetch upload streaming makes that simpler.
