Sets this subscription's maximum update frequency. This can be done while a subscription is streaming data in
 order to change its update frequency limit, but an actively streaming subscription cannot switch between filtered
 and unfiltered dispatching, and {TableModificationNotAllowedError} will be raised if this is attempted. If {#mode}
 is `:raw` then the maximum update frequency is treated as `:unfiltered` regardless of its actual value.

 @param [Float, :unfiltered] new_frequency The new maximum update frequency. See {#maximum_update_frequency} for
        details.
