2020-12-09perf!: centeral timekeepingUri Shaked10-211/+173
This should improve performance, especially when running simulations with multiple peripherals. For instance, the demo project now runs at ~322%, up from ~185% in AVR8js 0.13.1. BREAKING CHANGE: `tick()` methods were removed from individual peripherals. You now need to call `cpu.tick()` instead.
