docs: Request the maximum of an Array over any number of axes.
  
      .. note:: Currently limited to operating on a single axis.
  
      Parameters
      ----------
      a : Array object
          The object whose maximum is to be found.
      axis : None, or int, or iterable of ints
          Axis or axes along which the operation is performed. The default
          (axis=None) is to perform the operation over all the dimensions of the
          input array. The axis may be negative, in which case it counts from
          the last to the first axis. If axis is a tuple of ints, the operation
          is performed over multiple axes.
  
      Returns
      -------
      out : Array
          The Array representing the requested max.
