Add support for automatic decompression of gzip and deflate encoded
HTTP responses via the `auto_decompress` option.
When enabled:
- Adds `Accept-Encoding: gzip, deflate` header to requests
- Automatically decompresses response body based on Content-Encoding
- Supports gzip, deflate, and x-gzip encodings
- Graceful fallback for uncompressed or unknown encodings
Usage:
hackney:request(get, URL, [], [], [{with_body, true}, {auto_decompress, true}])
The decompression is performed when reading the full body via body/1.
Streaming responses (stream_body) are not affected by this option.
