Open ADI-2 Control 0.2.0

New

• Headphone EQ tab: an EQ for the ADI-2's five bands (optionally Bass/Treble) from AutoEq's
  headphone measurements (736 models, shipped with the app) or your own measurement file, and a
  target curve. Apply it to an output, store it as a preset, open it in the preset editor or
  save it as .adieqpr. Same fitting as ADI-2-Pi's headphone EQ.
• EQ preset files: import and export of ADI-2 Remote's .adieqpr files (EQ Presets →
  Import…/Export…).
• A/B in the preset editor: after Listen, switch the output between its previous EQ (A)
  and the preset (B).
• Several units: saved connections, switched in the top bar or the tray menu.
• Volume limit profiles, switchable in the tray menu.
• Command line and D-Bus control: open-adi2-control get|set|setup|preset|refresh …, and the
  same over D-Bus (io.github.shells_dw.OpenAdi2Control). See the README.
• Keyboard shortcuts in the window (↑/↓, Page ↑/↓, M, D, E, 1–9, Ctrl+Page ↑/↓, ?).
• Light theme and compact layout (Settings → App); dark stays the default.
• The page follows the output whose volume is turned on the unit (Settings → App, on by
  default).
• Unit status in Settings → Unit: device mode, balanced phones, DSD, AES/SPDIF input signal
  (Pro models), raw status words.
• Everything is read again after resume from sleep and after the screen is unlocked.
• ADI-2-Pi 1.0.0 "key needed for changes only": without a key the app shows the unit
  read-only with a View only badge and asks for the key at the first change. A link to
  ADI-2-Pi next to the connection setting.
• .rpm packages for Fedora/openSUSE; an AUR PKGBUILD and a Flatpak manifest in packaging/.

Changed

• Loading a setup asks for confirmation (window, tray menu, shortcut).
• A preset stored without a name is named "Preset N" (its slot).
• Settings from 0.1.x are converted on the first start (connection → saved connections, volume
  limits → the profile "Default").

Fixed

• ADI-2-Pi: commands were sent up to 50 ms late; the client now wakes for them at once.
