WriteAll saw 127GB allocs in a 5 minute timeframe for 4MiB buffers used by `io.CopyBuffer` even if they are pooled. Since all writers appear to write byte buffers, just send those instead and write directly. The files are opened through the `os` package so they have no special properties anyway. This removes the alloc and copy for each operation. REST sends content length so a precise alloc can be made.
