Support to uncompress data based on Content-Encoding

[EduFrazao]

Feature
When downloading large files via HTTP/S, its a common pratice to compress some of them base on their compress ratio, like large JSON or other text files.

Motivation
Supporting decompression of common algorithms used by http servers, like gzip or deflate will bring a more user friendly feature and with the potential of speed up decompression as it can be done while streaming the current download.

Details
The only know alternative is uncompress the file after downloading it, checking their Content-Encoding.
