streamFile :: Middleware

Convert ResponseFile type responses into ResponseStream type

Checks the response type, and if it's a ResponseFile, converts it into a ResponseStream. Other response types are passed through unchanged.

Converted responses get a Content-Length header.

Streaming a file will bypass a sendfile system call, and may be useful to work around systems without working sendfile implementations.
