Minor Changes

• c9c3c59: Time: metronomeClicks(tempo, changes, until, rhythm) gives the clicks of a metronome in seconds through the time-signature changes, the first of each bar accented, so a host can schedule them on the audio clock.
• c9c3c59: Playback: @audio-ui/core/playback plays an arrangement's audio clips on the audio clock, to the frame. A PlaybackState counts both sides in whole frames, so a loop of any length never drifts; TrackRenderer is a track's player, which copies a recording bit for bit at speed 1, reads it through a cubic interpolator when warped, folds a looped clip, mirrors a reversed one, fades a stop or a jump over 2 ms, and keeps a track that heard of a play late in step; CLIP_PLAYER_WORKLET is that player as an AudioWorklet module, whatever the bundler, which answers a sync once it has every message before it, so an offline render can wait for its players before it starts. The mixer's arithmetic comes with it: panGains (constant power, 0 dB in the centre and +3 dB at either end, each channel on its own gain), soloState and delayCompensation.
• c9c3c59: Device: an instrument's noteOn(note, timing?) and noteOff(timing?) take an optional NoteTiming, { at, id }. at is a time of the audio clock, so a host that schedules notes ahead plays them on the frame they fall at instead of when its timer fires; id names the note, so a noteOff for a note that another one took over from lets nothing go. With no timing, both act now on the held note, as before.
