Brotli returns a Handler that adds brotli compression to all requests.
Make sure to include the brotli middleware above other middleware
that alter the response body (like the render middleware).
type Options struct {
// CompressionLevel indicates the compression level, possible values are between// 0 to 11 (from best speed to best compression). Default is 5.
CompressionLevel int
}
Options represents a struct for specifying configuration options for the
brotli middleware.
