Title:

• Removed compression for node runtime since its buffering the response during streaming

Description:

• Removed compression middleware if runtime is node
• Removed content-encoding header to disabled compression for node

Motivation:

• Adding compression middleware buffers the response while streaming, defeating the purpose of streaming

Related Issues:

• Request to stream a chat completion results in buffered response instead of stream #290

Actually I am using image where I also disable it. I would propose completely removing it. The benefit is less than the pain it can cause, and in the context of streaming it's not giving much anyways.

Streaming is very important, please implement this or another fix.
