With the MCU Pro, the button labelled "Instruments" uses the Dyn button ID.
The one labelled "Audio Instruments" does not.
This may break Nucleus support - needs to be checked
Fixes all kinds of miscellaneous issues with MCP. Also removes several theoretical pan modes, replace "Tracks"
pan mode with "Trim", and takes a tiny step towards view modes
* fixes Master Fader Touch button in the Mackie;
* implements a MasterFaderTouch global button;
* removes unused MackieControlProtocol::_transport_previously_rolling property;
* implements DeviceInfo::get_global_button() method;
* creates GlobalButtonsInfo and StripButtonsInfo types in DeviceInfo;
* implements Surface::_last_master_gain_written property to help master fader feedback;
* makes Surface respect _mcp.device_info().strip_cnt() to create master fader and when connecting signals for strips and master fader instead of using hardcoded 8;
* removed a few unnecessary updates in Surface::turn_it_on();
* included master_gain_changed() in Surface::periodic();
* implemented MackieControlProtocol::master_fader_touch_press and
* MackieControlProtocol::master_fader_touch_release;

* implements Metering on/off through Button::Read as per Seablade's suggestion. I choose this button as it's the "Show meters" button in Traktion;
* removes redundant code from Meter::update_transport_rolling();
* renames Meter::update_transport_rolling() to Meter::notify_metering_state_changed();
* renamed Surface::notify_transport_state_changed() to Surface::notify_metering_state_changed();
* renamed Strip::notify_transport_state_changed() to Strip::notify_metering_state_changed();
* created MackieControlProtocol::notify_metering_state_changed() and made MackieControlProtocol::notify_transport_state_changed() use it;
* implemented turning off of timecode display and two char display in Surface::zero_all ();
* implemented master fader zeroing in Surface::zero_all ();
* calling Surfaces->zero_all() at MackieControlProtocol destructor;
* implemented restore of 2nd LCD line content after metering being active.
