- added counting of dropped packets sent/received
- duration of main loop on average and max duration

- safety checks on continuous packet mismatch
- lowered all sending timeouts to 5 ms
- better ACK/NACK propagation

(preliminary),

Inhale valve frequency changed to 500 Hz on nodemcu header, best PID parameters updated on CommsDebug.py, longer fill time for the testing

- could happen if started reading random trailing packet and first got stop flag

- wrong data assignment
- removed printing
- improved data retrieving

- payload now does not depend on data type, just provides simple wrapped
- moved struct definitions to common.h

constructor

tnow = static_cast<uint32_t>(millis());
if (tnow - time > timeout) {

deals with buffer overflow and forces all to be uint32
