fix #76
2020-12-12perf(cpu): speed up event systemUri Shaked2-18/+59
ditch `array.sort()` and instead manually keep the array sorted when we insert a new item.
2020-12-12test(cpu): fix implicit any errorUri Shaked1-3/+5
2020-12-12fix(cpu): event system issueUri Shaked2-2/+63
`updateClockEvent()` and `clearClockEvent()` would sometimes mess up the list of events. This could cause unexpected behavior when you have multiple timers running. Also added regression tests for these methods.
2020-12-12fix(timer): Incorrect count when stopping a timerUri Shaked2-18/+41
fix #72
2020-12-09perf!: centeral timekeepingUri Shaked12-221/+222
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.
