At least http-client and http-streams should support this use case easily,
you'll just have to parse the stream yourself. The easiest way is to write
a parser using attoparsec and lift that into a stream transformer. The
io-streams library has native support for this (
conduits supply a similar thing in the conduit-extra package.
