This has been pinned since the Go modules migration, because the
nytimes gzip handler was modified in version v1.1.0 in a way that
is no longer compatible.

Pretty sure it is this commit: https://github.com/nytimes/gziphandler/commit/c551b6c3b4b976eafa1a18220b5e21692784d8e2

Instead use handler.CompressHandler from gorilla, which is a web toolkit we already
make use of for other things.
