Make the Bitcrusher and Delay plates shorter (#399, #393)

Both devices were 280 tall, but their knobs end well above that. The
gap between the lamps or levers and the knobs was wide, and below the
knobs about 70 units stayed empty.

- The Bitcrusher is 680x220. Its knobs sit 14 higher, closer to the
  row of bit lamps.
- The Delay is 680x224. Its knob groups start 16 higher, closer to the
  two levers.
- The screen's frame is now worked out from the plate's bottom edge.
  It stays as far from the bottom as from the side, so the screen
  shrinks with the plate (116 and 120 tall).

Tests:
- crusher-view and delay-view: 30 tests green
- e2e 34 on melektaus-atx: ALL PASSED, 144 checks
- gate on melektaus-atx: 293 files, 4495 tests
