Constant rotor_http::client::MAX_CHUNK_HEAD

pub const MAX_CHUNK_HEAD: usize = 128

Maximum length of chunk size line. it would be okay with 12 bytes, but in theory there might be some extensions which we probably should skip

Note: we don't have a limit on chunk body size. In buffered request mode it's limited by either memory or artificial limit returned from handler. In unbuffered mode we can process chunk of unlimited size as long as request handler is able to handle it.
