[LAD] zita-jacktools update

[Fons Adriaensen]

Hello all,

A new release of zita-jacktools is available at
<http://kokkinizita.linuxaudio.org/linuxaudio/downloads>.

>From the README:

Changes since the first release:

* General code cleanup.
* Python docstrings for all classes.

* New class: JackLR4filt

   * 4th order Linkwitz-Riley or Butterworth filters,
     with delay and gain. 
   * Typical use is crossover filters, also useful
     for some measurements.

* Bugfixes:

    * JackAmbrot: fixed a nasty bug which produced incorrect
      rotation matrices. This also affected JackAmbbin.

* Some small changes:

    * JackSignal: 'nskip' and 'nloop' are now supported for
      both set_input_data() and set_output_data(), and must
      be keyword arguments.

    * JackGainctl: the 'rate' parameter is no longer supported.
      See the class docs for how exactly gain changes are done.
 
* Some new examples, among them a PyQt5 application using JackMatrix.     


Ciao,
