rr, aka RestartReader
RestartReader allows you to read bytes from an io.Reader without removing them.
RestartReader wraps io.ReadCloser or io.Reader and implements it. It holds the data from every Read in a buffer, and allows you to call .Restart(), causing subsequent Read calls to start from the beginning again. This is useful when you need to read the first few bytes of a stream or file, before passing off the full data to another function.
Import it with:
