Media Ctrl x0.3.0 (beta)

The first public beta of Media Ctrl. Everything is over Bluetooth now. The USB cable powers the board and is used for flashing and diagnostics.

What's new

• Three devices at once. An iPhone, an iPad and a Mac stay connected together, and the board remembers six.
• Devices screen. Hold the top right of the screen to see every connected and saved device, tap one to switch, pair another, or forget one. The board also follows whichever device starts playing, and pausing never moves it.
• Forget one device without disturbing the others. About's button is now Forget all devices.
• The top right names the device: "Spotify iPhone", "YouTube iPad".
• Mac over Bluetooth: play/pause, previous, next and volume, sent to whichever app played last. No track info yet; a Bluetooth helper is planned.
• New look: amber play button, a volume slider, and a More button.

Flash it

• media-ctrl-x0.3.0-cyd2usb.bin at 0x0: a clean install. Devices paired before need to forget Media Ctrl and pair again.
• media-ctrl-x0.3.0-cyd2usb-app-0x10000.bin at 0x10000: an update that keeps pairings.

Or use the browser flasher on the Flash it page in Chrome or Edge. For the USB-C / 2-USB Cheap Yellow Display (ESP32-2432S028R).

Beta notes: Windows and Android are untested. The Windows helper in windows-helper/ isn't used yet. See the docs and the changelog.
