docs: LimitStream limits the output to `n` bytes/objects
  If LimitStream is in object mode, it will skip over entries in Transform.
  If LimitStream is in data mode, it will skip over bytes
  
  @param {Integer} n - The number of bytes/objects to limit by
  @param {Object} options - Stream options object
