Added a tuner and a drone
Added a tuner that measures your instrument's pitch through the microphone, and a drone that keeps playing a reference note. Open them from Tuner and Drone in the menu, or with the U and ⇧D keys.

Changes
- The tuner shows the nearest note and octave, the offset in cents, and the frequency. Within ±5 cents it shows "In tune". It measures down to the low E of a 4-string bass.
- The tuner's meter can be a linear scale or an arc. The needle moves smoothly with the reading.
- The drone keeps playing a note you pick from the 12 notes and octaves 2 to 5, as a sine wave or an organ-like sound. It plays only while it is open and stops when you close it.
- You can set the reference A4 from 415 to 466 Hz. The tuner and the drone each keep their own, and Reset returns it to 440 Hz.
- Footer controls in Display Settings can add TUNER and DRONE buttons to the bar at the bottom of the screen. With a button in the bar, the tuner or drone opens as a panel above it, like TIMER and TAP, even from the menu or the keyboard. Without it, they open in the middle of the screen without covering the bar, so you can still press START.
- Added keyboard shortcuts: open / close tuner (U) and open / close drone (⇧D).
