invalid header check when Content-Encoding: deflate and it's raw deflate.

Should be using zlib.createInflateRaw.

Why?

Decompress either a Gzip- or Deflate-compressed stream by auto-detecting the header.

Because this method detects based on the binary header.
But I encountered deflate responses without headers, which only inflateRaw could parse.
If the Content-Encoding says deflate, then we do not need to auto-detect, we already know the answer.

The problem is that you cannot always trust the content encoding either (internet reality is messy). It's generally safer to rely on the binary header. But I guess the code could fall back to inflatRaw if Content-Encoding: deflate and unzip fails.
