* Rework timer_queue and monotonic architecture Goals: * make Monotonic purely internal * make Monotonic purely tick passed, no fugit involved * create a wrapper struct in the user's code via a macro that then converts the "now" from the tick based monotonic to a fugit based timestamp We need to proxy the delay functions of the timer queue anyway, so we could simply perform the conversion in those proxy functions. * Update cargo.lock * Update readme of rtic-time * CI: ESP32: Redact esp_image: Too volatile * Fixup: Changelog double entry rebase mistake --------- Co-authored-by: Henrik Tjäder <henrik@tjaders.com>
