Implement jack_lsp and a2jmidid for map automatically midi ports

> You need to start a2jmidid to get MIDI-ALSA ports automaticly mapped to JACK-MIDI ports.

Maybe is not necessary reimplement jack_lsp. Maybe using a2jmidiid, jack-client python will discover midi ports

Other option is use `MOD utils.get_jack_hardware_ports` for discover the hardware ports
