fix: support for compressed content in download2stream method. (#353)

Fixes #352 .

By switching from `iter_raw` to `iter_bytes`, **httpx will automatically
handle the decompression** if the `Content-Encoding: gzip` header is
present. If the header is absent or specifies no compression (like
identity), `iter_bytes` will yield the original bytes, just like
`iter_raw` would have.
